單周控制的單相交流斬波調壓電路

摘要：闡述了單周控制用于單相電壓交流斬波AC/AC轉換器工作原理，并利用Matlab/Simulink軟件對并聯型轉換器Buck電路建模并進行仿真，給出了電阻性負載穩態及突變情況下的仿真結果，證明在原理上是可行的。 敘詞：單周控制 AC/AC轉換器 單相 Buck電路 斬波 仿真 Abstract：Operation principle of single phase voltage AC/AC converter with chopping under one-cycle control is described. A simulation with Matlab/Simulink is completed for the AC/AC converter of parallel-type. It shows simulation results when the AC/AC converter carries constant resistive load and abrupt-change load, and proves that the scheme is feasible in principle.
