摘要
This paper investigates a PWM inverter for an adjustable speed drive using wide band-gap devices. First, the relationship between the carrier frequency of the PWM inverter and the volume of an EMC filter is clarified by simulation, besides the relationship between the carrier frequency and the volume of a cooling system. As a result, the total volume of the inverter system that contains an EMC filter and a cooling system will be reduced by 81.6% at the carrier frequency of 300 kHz. In addition, the conduction noise is measured from a prototype of the PWM inverter that is constructed by GaN-FET. Furthermore, the total volume of EMC filter for GaN-FET inverter system is reduced by 70% with a 300-kHz carrier frequency compared to a 10-kHz carrier frequency.
