摘要

提出了一种新的三相三开关开关整流器(SMR)控制方案。为了实现每相的统一功率因数输入，根据相应的相电流斜率确定三相SMR中开关的占空比。完全不需要电流传感器。SMR具有成本低、电路简单等优点。实验验证了所提方案的可行性。

A novel three-phase switch-mode rectifier without current sensors

A novel control scheme for a three-phase 3-switch switch-mode rectifier (SMR) is proposed in this paper. To achieve unity power factor input in each phase, the switches' duty ratios in the three-phase SMR are determined based on the corresponding phase current slopes. No current sensors are required completely. The SMR has the benefits of low cost and simple circuitry. Experiments are conducted to verify the feasibility of the proposed scheme.
