WARP Speed IGBT - International Rectifier

IGBTs are voltage-controlled power transistors, that have higher current densities than equivalent high-voltage power MOSFETs. (International Rectifier now with Infineon)

WARP Speed IGBT - International Rectifier

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
600V Warp 60-150 kHz Discrete IGBT in a TO-247AC package

WARP Speed IGBT - International Rectifier

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)

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

The DC models support operation in Constant Current, Constant Voltage, Constant Resistance or Constant Power mode as well as a short simulation. Engineers have ultimate control of current waveforms by using either the analog input or CC dynamic mode. An analog input (single input DC models) allows arbitrary current waveforms up to 20kHz with an external 0-10V signal........
