Air Conoditioner



•PFC
- - 30~60kHz of switching frequency
- - Single PFC or Interleaved PFC
- - Eoff > VCE(sat) loss > Eon loss for CRM IGBT
- - VCE(sat) loss > Eon loss > Eoff loss for CCM IGBT
- - Low Trr of FRD
•Inverter
- - 17~20kHz of switching frequency
- - MOSFET up to 3kW, IGBT over 5kW
- - High threshold, low trr, short circuit, etc., are needed
