Double-Hysteresis Current Control Strategy of Three-phase Voltage-type PWM Rectifier

摘要：

To maintained the merits of the traditional hysteresis, and at the same time, hold back the change of switching frequency and reduce the switching power loss in hysteresis control of PWM rectifier, based on the relationship between line currents and switching status, an improved algorithm of double-hysteresis current control method for three-phase voltage-type PWM converter was proposed. In the strategy, the position of reference voltage vector can be detected by double hysteresis; PLL circuit can detect the output of switching states. The proposed algorithm not only maintained the merits of traditional hysteresis, such as quick current response and current limited capacity, but also, it can overcome the drawback of non-fixed switching frequency of traditional hysteresis. The algorithm has been simulated and verified by MATLAB/simulink platform, and the system operates stably.
