摘　　要： 介绍了一种具有容错能力的单相正弦波逆变系统。在诊断单相正弦波逆变器功率开关触发脉冲丢失故障的基础上,对故障后电路采用主动容错控制策略,将电路拓扑进行重构,使单相正弦波逆变器在功率开关触发脉冲丢失故障状态下仍可保持良好的性能,提高了逆变器的可靠性和质量。 A single-phase sine wave inverter is presented which has the fault tolerant ability.The fault mode investigated is the case in which a misfiring does occur in one of the power switches.The fault tolerance is obtained by reconfiguration of single-phase sine wave inverter topology.This allows for continuous operation of the inverter even misfiring does occur in one of the power switches.Experimental results demonstrate the validity of the proposed system.
