数字平均电流模式控制三相六开关Boost PFC整流器中PI型电流控制器的性能分析与改进

In this article, the performance of the proportional–integral-type (PI-type) current controller in the digital average current mode (ACM) controlled three-phase six-switch (3ph-6s) boost PFC rectifier is analyzed with the consideration of the effect of the dead time, the time delays, and the dc offsets of the sampled input voltages/currents. Current control model is established to analyze the effe...
