IR 600V IGBTs promise higher power density for motor drive applications

International Rectifier has introduced a family of 600V insulated-gate bipolar transistors (IGBTs) optimised for motor drive applications operating below 10kHz including compressors for refrigerators and air-conditioners.

IR’s latest generation Gen7 F devices employ punch-through Trench technology to deliver higher power density and the ability to optimise conduction and switching losses for a specific frequency of operation.

The new IGBTs achieve very low VCE(ON) to improve efficiency with zero temperature coefficient for high efficiency across the entire operating range.

The devices also promise smoother switching to reduce EMI and overshoots, and are short-circuit rated for motor drive applications.

The IRG7RC10FD and IRG7IC30FD are co-packaged with a soft recovery diode while the IRG7SC12F is a single IGBT that allows the designer to choose a specific diode for the application.

Two motor control reference designs featuring Gen 7 F IGBTs are available.

The IRMDKG7-400W features the IRG7SC30FD DPAK IGBT and IRS2334S 3-phase HVIC driver for motors up to 400W.

The IRMDKG7-600W features the IRG7SC30FD DPAK IGBT and IRS2334S 3-phase HVIC driver for motors up to 600W. Both reference designs include an optional heat-sink.
