摘　　要：给出了一种恒压恒频正弦波逆变器波形控制的调节器设计方法,进行了逆变器电压控制回路比例+谐振(PR)交流调节器的设计,分析了以准谐振交流调节器实现的逆变器控制回路对交流参考信号相位无差和幅值近似无差跟踪的原理,讨论了谐波来源问题,以及与系统参数的关系,通过根轨迹法给出了调节器参数的设计,针对非线性负载下输出波形的谐波失真问题,给出了谐波补偿回路的参数设计。较好地解决了恒压恒频正弦波逆变器的波形无差跟踪问题,以及对整流性负载等非线性负载的条件下的输出电压谐波失真的补偿问题。A new control method of constant given by alternative current proportional and vohage and constant frequency （CVCF） sine waveform inverters was resonant （PR） regulator, and the alternative current PR regulator of the inverter vohage main-control loop was designed. The control principle of phase error free and amplitude approximate error free to AC reference signal was analyzed. The relationship between the harmonic sources with the system parameters was discussed, and the parameters design of the PR regulator was given through root locus method. For output waveform harmonic distortion problems of the inverter non-linear load, the regulator type and design parameters of the harmonic compensation circuit were given and stability was discussed. The experiment circuit was designed, and the PR regulator was realized by the TMS320LF2407A. The validity of the designing and analyzing method were proved by the experiment.
