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.

Other products are DC Power supplies AC Power Sources, Modular AC/DC Units. Services like Compliance Testing and Custom Products.

AMETEK Programmable Power

SLM Family Electronic Loads - The SLM family includes 11 models of fully programmable, single input AC or DC modular electronic loads. DC models are offered to test power supplies, battery chargers, battery discharge, power supply transient response and integration into ATE systems. AC models are ideal to test low power inverters.

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........
