PCIM: Rohm’s 1.2kV IGBTs drop only 1.7V

Rohm’s automotive grade 1,200V IGBTs are aimed at inverters used in electronic compressors and for switching positive temperature coefficient (PTC) heaters. RGS series parts are AEC-Q101-compliant and come in 1.2kV and 650V variants. “Increasing the number of electric vehicles advances the need for electric compressors often driven with IGBT’s,” according to Rohm, and “the demand ...

Imec integrates half bridge and drivers on a single GaN IC.

Imec has demonstrated a functional GaN half-bridge monolithically integrated with drivers. Mounted on a buck-convertor test board, the chip converts an input voltage of 48 Volt to an output voltage of 1 Volt, with a pulse width modulation signal of 1 MHz. The achievement leverages on Imec’s GaN-on-SOI and GaN-on-QST technology platforms, reducing parasitic inductance ...
