三相PWM整流器直接功率预测控制
The Direct Power Predictive Control of Three-Phase PWM Rectifier
This paper established the mathematical model of the three-phase voltage-source PWM rectifier and analyzed the principle of the direct power control, in order to overcome the unstable frequency switching and poor stability of traditional direct power control, a predictive direct power control (P-DPC) method combined with space vector control strategy is designed and verified through simulation. The research and simulation analysis show that the application of P-DPC makes the system own the features,like simple structure and algorithm, good dynamic response, high power factor, constant switching frequency and low THD.
