Study of on Three-phase Reversible PWM Rectifier without Phase Angle Detection

详细分析了同步模式下三相可逆PWM整流控制方法,提出了一种无相位传感器控制策略。通过和有相位传感器以及其他无相位传感器方法实验结果比较,该方案有很好的控制效果。这种方案不需添加额外的硬件设备,控制方法简单,能有效降低系统的成本。

This paper analyses the theory of three phase reversible PWM rectifier and presents a control strategy without phase angle detection with the process of the design. Through comparing the different ways, the result of waveforms has proved that this control strategy gives good performance. Without modification of the topologies and requiring any additional hardware, this control strategy is very simple and can reduce the cost of the system.
