Product Description

IGBT Power Supply

Rectifiers circuit takes the secondary current that is AC from the wall supply and convert it into a direct positive current that is DC. Many products and other hand made tools use direct current. The rectifier is used to provide direct current to the application as required.

What IGBT rectifier is?

High frequency switching IGBT rectifier have three phase. First, AC input to convert DC by rectification and filters. After that, DC voltage is change to DC output by shift phase that is full bridge PWM DC/DC converter. And at last, the power has independent power modules each module work independently or produce power in parallel connection.

Advantage of IGBT rectifier over the SCR

An IGBT (insulated-gate bipolar transistor) uses high frequency switching and PWM (pulse width modulation) technology for current and voltage regulation with a SCR (silicon controlled rectifier) uses relatively low frequency switching and phase shift technology. As it uses high frequency of operation, the transformers used in circuits having IGBT, scan even the tiny and lighter weight particles also. Hence, IGBT based power control circuit are lighter weight, smaller size, cost effective, energy effective as compared to SCR based control circuits.
Nowadays IGBTs widely replacing SCRs because of their advantages and cost effective qualities.

As, we compare IGBT rectification with SCR rectifier, IGBT has many advantages, such as :-

  • Low investment and maintenance cost.
  • Because of higher conversion efficiency, low DC output voltage it save more 20% energy.
  • Because of high frequency pulse output it require less electroplating time.
  • Compact size, 1/3 as compared to SCR size.
  • Higher power factor >0.94 avoid government fine due to low power factor.

 

Power range of rectifier

  • Input AC 3 phase voltage: 380V, 415V, 220V, 480V
  • Output DC rated voltage: 6-400V
  • Output DC rated current: 500A-20000A
  • Output DC rated power: 5kW-500kW

 

Cooling option

  • Water Cooling
  • Forced Water cooling

 

Water Cooling vs Forced water cooling

Water Cooling Advantages

  • minimal cost.
  • smaller size.
  • suitable corrosive environment; cabinet sealed.
  • effective cooling even under the high temperature, up to 50 Celsius.
  • Better cooling effect for high power rectifier.

 

Disadvantages

  • Need own time for cooling water.

 

Forced Air Cooling

Advantages:

  • user friendly; doesn’t require extra time for cooling.
  • Suitable for low power rectifier.

 

Disadvantages:

  • expensive as compare to water cooling.
  • Cooling effects are not much effective as compare to water under higher temperature up to 40 Celsius.
  • The acid corrosive gas may damage internal parts of rectifier and affect the reliability, if rectifier is put closer to electroplating.
