摘　　要：非线性负载会在三相车载逆变电源系统中引入谐波,损伤用电设备。为了降低逆变电源输出电压谐波含量,文章研究了基于准比例谐振控制算法的谐波抑制方法 ,主要抑制电源输出的5次和7次谐波。通过仿真模型和实物试验,测试了传统瞬时控制方法和准比例谐振控制方法的差别。结果表明,准比例谐振控制方法既能消除输出电压中的特定次谐波,又可满足系统动态响应性能和稳态精度要求,具有良好的谐波抑制效果。Nonlinear loads introduce harmonics into the three-phase inverter power system, which damages the electrical equipment. In order to reduce the harmonic content of the inverter output voltage, a harmonic suppression method based on the quasi-proportional resonance control algorithm was proposed. The proposed method mainly suppresses the 5 th and 7 th harmonics of the inverter output voltage. The traditional instantaneous control method and quasi-proportional resonance method were tested by simulation models and physical experiments. Results show that the quasi-proportional resonance can eliminate specific harmonics in the output voltage, meets the requirements of system dynamic response performance and steady-state accuracy and has a good harmonic suppression effect.
