Plating rectifier 100A

Plating rectifier has important position in plating machine area:

Electroplating is an electrolytic process. Needless to say, the performance of its power supply, type, characteristics and other factors will have a significant impact on electro plating process. Especially today with the rapid development of modern electroplating technology, plating rectifier has more important position. Therefore, understanding the impact of electro plating rectifier to plating process is very necessary.

Which is a new type electro plating machine plating rectifier – high frequency switching power supplies. It combines advantages of silicon rectifier waveform smoothness and silicon controlled rectifiers voltage easy adjustment, while has highest current efficiency (up to 90%), the most smallest volume, and needless to say, it is the most promising plating rectifier. Manufacturing technology has solved the power problem, thousands of amperes power switching plating rectifiers have entered a practical stage of application.

Plating rectifier conversion:

Make the AC grid by EMI anti electromagnetic interference filter, direct rectification, filtering wave, by mean of inverter convert DC voltage into tens or hundreds of KHz square wave frequency, and then by high frequency transformer isolation, reduction voltage, then by high-frequency filter output DC voltage. After sampling, comparison, amplification and control, the drive circuit and power converter controls duty cycle of IGBT, obtained a stable output voltage (or output current).

Electroplating high-frequency switching plating rectifier main conversion structure has: forward converter, half bridge, full-bridge, etc., have pulse-width modulation (PWM) “hard switch” circuitry,also have popular phase-shift control “soft switch ” power circuit.
Pulse width modulation (PWM) HF switching plating power supply, its operating frequency mostly below 50 KHz, with a voltage or current feedback control.It change the drive voltage pulse width to alter output current by interrupting power flow and adjust the duty cycle method, make the device working in the “hard switching” state, ie forcing conduction (voltage is not zero) or forced shutdown (current is not zero), making the switching power transistor both exist high pressure and large current cross when switch on and off, therefor switching loss less, peak interference strong.

High press peak arose by transformer leakage inductance and high current change rate, not only easy to damage the power tube, also produce significant electromagnetic radiation, that reducing the reliability and power efficiency.Switching power supply plating rectifier frequency has reached audio frequency, through filtering wave to realize low ripple wave output is more easy. And further more, steady current and voltage functions easier to achieve.

DC power supply

DC power supply

How to choose dc power supply?

To select dc power supply has three requirements:
1, Meet the specifications required by plating process, including dc power supply power, waveform index, adjustable current and voltage range, etc.;
2, DC power supply itself reliability power supply, which mainly refers to structure reasonable, security and line features, cooling methods;
3, DC power supply cost performance.

Determine what kind of DC power supply suitable for you:

Determining plating type and and what kind of dc power supply the plating tanks shall use is the implementation and the first important work in electroplating production. There are 2 methods to determine suitable dc power supply in the actual plating production:
One: according to plating liquid solution to determine volume current density;
Two: calculated according to the plating area to get plating current density per unit.

The so-called volume current density, it is based per liter of plating solution allowed to pass maximum current to adjust entire plating tank current intensity, to determine the maximum power supply output and the conventional output.

Example for choosing DC power supply:

Copper is generally 0.2 ~ 0.3A/L;
Nickel is 0.1 ~ 2.5A/L;
Bright nickel plating is 0.3 ~ 0.35A/L;
Acid zinc is A/L;
Alkaline zinc up to 1.2 A/L;
Chrome is A/L.
Bright nickel plating as case shows, 600L bath maximum process current up to 0.3A/L × 600L = 180A, so choose 200A DC power supply is just fine.

If according to plating area volume also can calculate the max. current.
We take chrome plating as case: if it is 600L plating bath, at 60 ℃, maximum current density of 100A/dm2, the plating tank at full load setting as 10dm2, then the power required maximum output current of 100A/dm2 × 10dm2 = 1000A, that is, 1000A DC power supply, 18V rectifier power supply.

After determining power of DC power supply. Also need consider plating technical treatment process requirements and plating site condition to select waveform, cooling method, volume size, and corrosion resistance, etc., including cost factors.

Plating power supply technology:

Plating power supply is to converter line frequency AC current into different voltage & frequency & waveform direct current equipment. In the thyristor plating power supply main apply “rectification” technology, while in high frequency rectifier switching power supply both use “rectification” and “inverter” technology. Plating power supply main formed by circuit and control circuit.

Plating power supply evolution:

Electro plating power supply provide power supply to a variety of plating bath. Plating can be divided into direct current plating, cycle pole reverse plating, and pulse electroplating etc.. Early plating power supply used by AC motors – DC generator units, since the 1980s has gradually been replaced of power electronic devices composed plating power supply.

Plating power supply voltage and ampere:

Direct Current plating power supply: low-voltage, high-current DC power supply voltage is generally not more than 48V, requiring continuous adjustable; output current can be up to thousands of ampere. Electroplating power supply powered directly by the city power. In order to improve the plating power supply machine’s power factor, DC electroplating power supply rectification current mostly adopting non-controlled rectifier circuit, but the voltage regulator is completed on the front side of main transformer AC voltage regulator. Considering the low voltage and high current of plating power supply, the rectifier circuit is often used with dual star balancing reactor circuit. Voltage regulator most stepless auto-transformers, motors can be used by remote control, the disadvantage is easy to wear brushes, regulators response slow by time. The disadvantage with stable reactor as a regulator is low power factor. With thyristor three-phase AC voltage regulator voltage regulator, there are also disadvantages of low power factor, but response speed and control results better than above type.

SMPS power unit 600A

600A SMPS

SMPS power unit:

SMPS power unit power supply (also referred to as switching Rectifier SMR) through the MOSFET or IGBT in the high-frequency operation, switching frequency is generally controlled within 50-100 KHz range, ripple factor≤1%, to achieve high efficiency and miniaturization.

SMPS power unit birth process:

1960s large-scale application of the linear regulator DC power supply, because it’s following disadvantages, such as large volume weight, it is difficult to achieve miniaturization, large loss, low efficiency, there are common end between output and input, which difficult to achieve isolation, it can only lower voltage, can’t increase voltage, so it is difficult in the case of the application of output greater than 5A, has begun to be replace by DC SMPS power unit.

In 1964, Japan NEO magazine published two articles instructive:
One article for the “high-frequency technology make AC variable DC power supply miniaturization”;
Another article “pulse modulation for power supply miniaturization.”
These two articles indicates SMPS power unit DC power supply miniaturization research direction, that is one high frequency, the second is the use of pulse width modulation techniques. After nearly 10 years of research, development and achieved good results.

SMPS power unit 20kHZ revolution:

In 1973, Motorola published an article entitled “Trigger from 20kHz of revolution”, all around the world set off a development boom of high-frequency switching power supply and DC/DC converter is used as a switching regulator switching power supply, the power density from 1~4 W/in3 increased to 40~50W/in3. First adopted Buck converter.

By the mid-1980s, Buck, Boost and Buck Boost converter is also applied to SMPS power unit. The mid-1970s, the California Institute of Technology have developed a new switching converter, called Cuk converter (based on the inventor’s name S1obodan Cuk). Cuk converter and Buck-Boost Converter with each other duality, also is a step- down converter. The mid-1980s and then gradually be applied to switching power supply.

In 1976, the United States P. W, Clarke has developed a transformer “primary inductance converter” referred to PIC, patented, and is also applied to the switching power supply.

In 1977, Bell Laboratories on the basis of the PIC, has developed a transformer “single-ended primary inductance converter”, short (with the transformer) SEPIC circuit, this is a new DC/DC single-ended PWM switching converter circuit is called dual DualSEPIC, or Zeta converter.

By 1989, people applied SEPIC and Zeta to SMPS power unit, making switching power supply used in the DC/DC converter, increased to 6 kinds. So far, through DC/DC converter and the cascade evolution, switching power supply used in DC/DC converter has been increased to 14 kinds. Use these 14 kinds of DC/DC converter as a switching power supply, it can be designed in different places, meet different performance requirements and applications, high performance, all kinds of power, high power density switching power supply.

Rectifiers control functions:

According to the requirements of electro plating process, the rectifiers of DC power supply is often to complete the following control functions:
Constant current automatic control, constant voltage automatic control, automatic constant current constant voltage control, constant current density control and ampere hour control.

Rectifiers input output voltage changing details:

In order to improve the power factor of whole rectifiers machine, silicon rectifiers adopt non control rectification, its output voltage/current feedback to the phase shift control. According to the different requirements of current and voltage for plating machine, change the thyristor voltage regulator phase shift control angle, therefore to change rectifiers input and output voltage, i.e., change the DC output voltage or current of rectifiers.

The electric power supply is different from the general electric power supply for steel plating machine. In the case of the plating process, the supply of a single phase alternating current can be adjusted, in the case of constant electric power, and by the exchange of the electric current, which is converted into direct current.

Using of large current density rectifiers:

In the direct current plating machine, metal ions in the electrolyte are obtained from the cathode which is plated on the cathode. Such that the concentration of metal ions in the electrolyte near the cathode is decreased, which slows down the rate of deposition. Therefore, the use of the larger current density of the current density rectifiers not only raise the speed of the plating, but the amount of hydrogen on the cathode increased, the current efficiency is reduced, and the quality of the plating coating deteriorated.
