摘　　要：不同的控制策略与实现办法决定着逆变电源输出波形质量和动态性能的好坏,传统的PI控制难以实现交流系统的无静差跟踪,系统的抗干扰能力也有所不足。为提升逆变系统的输出电能质量和动态性能,提出一种基于准比例谐振(Quasi-proportional Multi-Resonance,QPR)控制与重复控制相结合的复合控制方法。分析了LC型单相全桥逆变器的数学模型,建立了QPR控制与重复复合控制的框架。两者间采用并联控制,相比于单一控制策略,该复合控制同时兼顾了QPR控制动态性能与重复控制稳态性能的优越性。对负载突变有较快的响应速度,能够有效抑制周期性谐波,改善系统动态特性。仿真验证了所提方法的有效性,结果表明复合控制下的LC型单相全桥逆变器动态性能良好,在非线性负载下谐波输出电压THD降低了69.01%,负载适应性较强。Different control strategies and implementation methods determine the output waveform quality and dynamic performance of the inverter power supply.The traditional PI control is difficult to realize the non-static error tracking of the AC system,and the anti-interference ability of the system is also insufficient.In order to improve the output power quality and dynamic performance of inverter system,a compound control method based on Quasi-proportional multi-resonance(QPR)control and repetitive control is proposed.The mathematical model of LC single-phase full-bridge inverter is analyzed,and the framework of QPR control and repetitive compound control is established.Compared with a single control strategy,the composite control takes into account both the dynamic performance of QPR control and the steady-state performance of repetitive control.It has a fast response speed to load sudden change,which can effectively suppress periodic harmonics and improve the dynamic characteristics of the system.The simulation results show that the LC type single phase full bridge inverter under compound control has good dynamic performance,and the harmonic output voltage THD is reduced by 69.01%under nonlinear load,and the load adaptability is strong.
