摘　　要：为解决电力电子变流器在逆变器通断控制过程中会产生较多的电压和电流谐波成分的问题,针对逆变电源中的低次谐波,提出一种基于差分进化法的单相电压型逆变器SHEPWM控制方法;利用遗传算法确定载波的开关频率,并通过载波层叠策略实现级联逆变器的随机PWM控制,降低集中在逆变器开关频率及其整数倍频率附近的高次谐波峰值。For the power electronic converter in the inverter switch-off control process will produce more voltage and current harmonic components, and the low harmonics in the inverter power supply,a single-phase voltage inverter SHEPWM control method based on differential evolution is proposed by using the specific harmonic elimination pulse width modulation SHEPWM method.Then,the switching frequency of the carrier is determined by genetic algorithm,and the random PWM control of cascading inverter is realized by the carrier stacking strategy,which reduces the high harmonic peak concentrated near the inverter switching frequency and its integer multiple frequency.
