[Product Name] IGBT high power switch mode rectifier



[Product Description]



The rectfier adopts high frequency IGBT PWM modulation technology, and use phase shift full bridge soft switch technology, non-crystalline material magnetic core high frequency transformer, has high reliability, high efficiency, high power factor, small size, light weight etc. advantages.


Fully digital control method is used,upgrade output voltage and current stability and accuracy, easy to communicate with remote control through RS485,CAN, Profibus.


Transformer, power unit adopts water cooling or forced air cooling method.


Touch screen is easy for user friendly operation and reading, local/remote control, constant current/voltage is switched on touch screen, output digital number is easy to read.


Complete protections ensure safe, reliable and stable running.


[Working Principle]


3 phase AC input is rectified through 3 phase rectifier bridge, the output high voltage DC is inverted by IGBT full bridge inverter circuit, high frequency high voltage AC pulses are transformed to low voltage high frequency AC pulses through transformer, the low voltage AC pulses are rectified by fast recovery diode modules to DC current, output demanded voltage and current.

 [Output Type]





  • High efficiency, energy saving


Traditional thyristor power supply highest efficiency is only about 75%, 55%-65% at half load or light load. But IGBT switch mode power supply efficiency could be above 90% at full load, power loss is much less than thyristor rectifier, saving energy 20%-30%, reducing production cost greatly.


  • Environment friendly, less investment


High power factor(0.92-0.98), small pollution to electric network, no extra power factor corrector facility is needed, reducing user’s equipment investment.


  • Small size, light weight


Due to high frequency transformer is used, the size and weight is greatly reduced, saving user’s space and easy to move, install and transport.


  • High stability and high reliability


reasonable circuit design, mature control method and complete fault protections and alarms, reducing damage to the rectifier; strict production process, imported components, making the performance stable and reliable.


  • Digital control


Adopt full-digital control system, high-performance DSP control, flexibly controlled, has high control accuracy and high stability.


[Main Components]

Breaker, rectifier bridge module, IGBT module(Fuji or Infineon), high frequency transformer, capacitor, control transformer, water pressure transducer, water temperature transducer, switching power supply, touch screen, resistance, diode, digital control board


[Operation and Display]

  • Local by touch screen, remote by digital meters and potentiometer, switches



Detailed operation and maintenance manual supplied, with troubleshooting table

Touch screen provides self fault diagnostic facility for immediate analysis.
