摘　　要：提出了一种多环反馈加电流前馈的单相逆变器控制方案,该方案使单相逆变器在空载和负载情况下输出电压的幅值和相位均能完全跟踪正弦给定。文中介绍了该方案的理论依据,给出了参数计算方法,并搭建了一台40kVA的实验样机,实验结果验证了该方案的有效性。This paper presents the analysis and design of a multiple feedback loop control and current feedforward control scheme for single-phase voltage-source inverters (VSI). Employing the proposed scheme, the output voltage of VSI can follow the reference without steady-state error. The validity of the proposed scheme is proved by the experimental results on a 40 kVA single-phase system.
