Rectifiers

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.
