AC To DC Igbt High Frequency Voltage Power Supply

- Aug 28, 2020-



Essentially, a rectifier is an electrical device used to convert alternating current (AC) to direct current (DC) by allowing current to flow through the device only in one direction). The diode works like a one-way valve in the rectifier to maintain this current. Correction is a general way to describe this process.

Although rectifiers have many uses, they are most commonly used as major components of DC power and HVDC transmission systems. When it comes to rectifiers, we speak from an industrial point of view (contrary to pure electrical engineering, the term "rectifier" refers to anything that converts alternating current to DC). Therefore, the rectifier is usually specified in an industrial environment based on the applied voltage, the current required in the process, the quality of the power supply, and how you arrange the control.

ripple is an important index to determine rectifier efficiency. ripple is expressed as a percentage of power clarity (clarity). alternating current divided by dc equals ripple percentage. A clear measure of rectifier quality is a factor that organizations such as NADCAP,IATF require companies to measure.

At present, there are about 25 DC power manufacturers in the industrial market. Dynapower has been at the forefront of developing customized and standard rectifier solutions for the global automotive, aerospace, mining, water and waste treatment, steel, chemical, defense and finishing industries since its inception in 1963.


I believe most people are still using oil-cooled thyristor rectifier, oil-cooled SCR power supply is very good, but compared with switching power supply, IGBT rectifier has many advantages over SCR rectifier, so they are now more and more used in electroplating process. Replace SCR rectifier.

Why switching power supply is recommended, please refer to the following points:

1. cost reduction

High 2. conversion efficiency, power saving

3. running continuously for 7 days and 24 hours

4. compact, modular, compact

5.  Low pollution to power grid, power factor & gt;0.94

6. not affected by power fluctuations, output 100%, no additional capacity required
