| 摘 要： | 提出了一种单相Z源逆变器控制策略,该策略由Z源网络电压控制环、交流侧电压瞬时控制环和直流侧电压纹波前馈控制环3部分组成.由于Z源阻抗网络存在非最小相位效应,因此在Z源网络电压闭环控制基础上引入了交流侧瞬时控制,使逆变器获得了较快的响应速度.针对负载较重时Z源网络输出电压波动大的问题,通过电压纹波前馈控制修正调制比,有效抑制了直流侧电压纹波对交流侧的影响,提高了输出交流电压的波形质量.仿真及实验结果均证实了所提出的控制策略的有效性.

| Abstract: | The control strategy for single-phase Z-source inverter,which consisted of Z-source network voltage feedback,ac-side instantaneous feedback and voltage ripple feed-forward loop,was presented.Due to the non-minimum-phase effect of Z-source network,an ac-side instantaneous controller was incorporated based on the Z-source network voltage feedback loop to guarantee fast dynamic response.The Z-source network has voltage ripple during operating with the heavy load,which decreases the performance of the output vo... |
