New high efficiency transfer mold module with parallel IGBT and Super Junction MOSFET

Annual Performance Factor (APF) requirements which calculate the annual electricity consumption have been applied to applications such as air conditioners necessitating reduction in the power consumption of the semiconductor switches in the inverter. A new Super Mini DIPIPM™ with Super Junction MOSFETs in parallel with the IGBTs has been developed to meet these lower annual power consumption requirements. The on-voltage characteristic in the low current region is a key issue for APF because the power loss at light load condition represents a significant portion of the annual utilization of the inverter. The on-voltage at low current can be reduced by using SJ-MOSFETs in parallel with the IGBT switches. A reduction in power consumption at light load of 32% has been achieved.
