Optimization of IGBT in power factor correction module for home appliance

IGBTs in an application specific power factor correction module for home air conditioner, have been characterized in terms of the conducted and radiated EMI noise as well as static and dynamic loss. Simulation and experimental results showed that internal gate resistance and drift layer thickness should be optimized in terms of performance and EMI noises. System simulation predicted that total power consumption by IGBT, FRD and rectifier does not exceed 80 W even in worst condition; output power=3 kW, controlled output DC voltage=380 V, Vin=170 V and fs=25 kHz.
