DC-bus Voltage Control for Dual PWM Based on Comprehensive Reactive Power Current Target
DC-bus voltage control strategy of AC-DC-AC dual PWM converter system is researched. Based on original direct current control strategy for net-side rectifier in d-q synchronous reference frame, a novel reactive power current iq control strategy is proposed, which takes both the unity power factor and the DC-bus voltage stability together, as iq comprehensive regulating target, using a fuzzy controller. Simulation results indicate that the reactive power current iq dose quick up the response speed of active power current id, and the DC-bus control performance is improved.
