摘　　要：针对变频器功率开关管容易发生单相短路及开路故障的现状,采用意法半导体公司的STM32F103VBT6设计了一种容错型逆变器。通过对实验平台的测试得出变频器在发生故障以后,能够在三相四开关SVPWM状态下正常工作,增加了变频驱动系统的可靠性。A kind of fauh-tolerant inverter with STM32F103VBT6 is designed to solve short-circuit and open- circuit fault. Through the test of the platform, it is proved that the inverter can work under three- phase four-switch SVPWM. It increases the reliability of the variable frequency drive system.
