High frequency rectifier development tendency:

Application in various power systems and power electronics, switching power supply high frequency rectifier technology are all at the core position. For large electrolytic plating power supply, conventional circuit is very large and heavy, if use high frequency rectifier switching mode power supply technology, which will be a significant decline in volume and weight, but also can greatly improve the power utilization efficiency, save materials and reduce costs. Electric vehicles and variable frequency drive, they are more indispensable switching mode high frequency rectifier power supply technology, electricity frequency changed by switching power supply, so can achieve nearly ideal load matching and drive control. High frequency rectifier switching power supply technology, also is all kinds of high-power switching power supply (inverter welding machine, communication power, high-frequency heating power, laser power supply, power supply operation, etc.) core technology.

High frequency rectifier frequency:

Theoretical analysis and practical experience shows that transformers, inductors and capacitors volume weight is inversely proportional to power supply frequency square root. So when we increase the frequency from 50Hz to 20kHz, increase 400 times, then the volume weight of electrical equipment is substantially reduced to 5 ~ 10% of frequency design. Whether inverter rectifier welder, or communication usage power supply switch mode rectifier, all show this basic principle. Similarly, the traditional “rectification industry” electroplating, electrolysis, electrical processing, charging, float charging, power closing with various DC power can also be transformed in accordance with this principle, a “class switching converter power supply”, the main material may save 90% or more, also saving electricity power at least 30% or more. Due to gradually increase the power electronic device operating frequency limit, prompting many of the original tube using conventional solid- frequency equipment, bring significant economic benefit in energy, water, economic saving materials, but also can reflect the value of this technical content.
