摘　　要：针对单相400Hz逆变电源系统的控制特点,引入输出电压瞬时值外环和电感电流内环的双环反馈控制,采用极点配置与PI控制相结合的方法对系统进行了设计,并根据状态空间理论建立了系统数学模型。仿真结果表明,该方案动态响应快、稳态精度高、THD小、带负载能力强。This paper presents the design of a single-phase 400 Hz inverter for the characteristic of 400 Hz inverter,the method of inverter instantaneous voltage and current PI controller is adopted.A hybrid pole configuration-PI control scheme for 400Hz inverters is presented.A mathematical model based on the state-space averaging and linearization technique is established.Simulation results indicate that the proposed control scheme can achieve good dynamic performance as well as steady-state performance.The THD is small,and the output voltage is steady as load changes.
