Abstract: Aiming at the widely used control scheme of inverter compressor, the loss components of power devices are analyzed and simulated. Based on the simulation results, the super-junction power MOSFET is proposed to be applied to inverter. The simulation and measured results both show that Cool-TechTM inverter technology based on super-junction power MOSFET can significantly reduce the heat loss of the inverter and improve the COP value of the inverter refrigerator products.
