基于交流比例积分控制器的单相逆变器

摘要

提出一种电感电流、输出电压瞬时值反馈控制和负载电流前馈控制相结合的复合控制策略。在此基础上,研制了一台800W的单相逆变器。实验结果表明,提出的控制策略改善了逆变器输出电压的波形,提高了系统的暂态特性。%A compound control strategy controlling of instantaneous current of the inductor, output voltage of the inverter and forward feeding load current has been proposed. A800W single phase inverter is developed. The results shows that the output voltage waveform is greatly improve and the dynamic performance is enhanced.
