摘　　要：分析了电压源型 IGBT-SPWM 逆变器输出电压和电流谐波及其产生规律,并提出了相应的谐波抑制策略,如选择正确的载波频率、精确实现选择的载波频率、在逆变器中注入谐波电流等,研究结果表明这些措施是可行的。This paper analyses the harmonics in output voltage and current of voltage-source IGBT-SPWM inverter and their developing law. The relevant strategies for restraining harmonics are presented in the paper, such as selecting appropriate frequency of carrier wave、accurately implementing of the selected frequency of carrier wave, injecting proper harmonics into the inverter and so on. The study results show the feasibility of the presented methods .
