WARP Speed IGBT - International Rectifier

IGBTs are voltage-controlled power transistors, that have higher current densities than equivalent high-voltage power MOSFETs.

WARP Speed IGBT - International Rectifier

IRG4PC40W -TO-247AC
Features Include
  • 2 to 2.5 times the current density of MOSFETs
  • Lower conduction losses at equivalent current rating compared to MOSFETs
  • Reduced current tail for high frequency operation
  • "Positive-only" gate drive
IRG4PC40W - 600V Warp 60-150 kHz Discrete IGBT in a TO-247AC package

Lower switching losses allow more cost-effective operation than power MOSFETs up to 150 kHz ("hard switched" mode)  

Of particular benefit to single-ended converters and boost PFC topologies 150W and higher 

Low conduction losses and minimal minority-carrier recombination make these an excellent option for resonant mode switching as well (up to >>300 kHz)  

WARP Speed IGBT - International Rectifier
The IGBT in TO-247 delivers the same efficiency at full loadas the MOSFET in the larger TO-247 package.

DC to AC Inverter - 500W - International Rectifier

DC to AC inverter converts DC voltage to a pure sinusoidal output voltage. This is used for UPS, solar inverters and frequency converters. This design operates without fan up to 500W.

DC to AC Inverter - 500W - International Rectifier

A full bridge topology is used to implement the DC to AC inverter. The switching frequency of the high side and low side IGBTs are 20 kHz and 60 Hz, respectively. This switching technique produces 60 Hz AC sine wave across the output capacitor.

DC to AC Inverter - 500W - International Rectifier

The Key IR Power Semiconductors are
  • IRGB4062DPBF (600V/24A Trench IGBT) High Side IGBTs 
  • IRG4BC20SD-PBF (600V/10A S-type Planar IGBT) Low Side IGBTs 
  • IRS2106S (600V half bridge driver IC)
One of the Benefits of the H bridge topology and switching technique.

"IGBTs are driven using high voltage gate driver IC with bootstrap technique. There is no separate floating power supply required for the high side drive. Bootstrap capacitors for these drivers get refreshed every switching cycle (50 usec) when current freewheels on the low side IGBTs copackage diodes."
