A predictive direct power control strategy for single-phase pulse-width-modulation rectifier(PWM) is presented.
With the actual single-phase input current and voltage, a virtual quartered current and voltage are constructed. Based on the
actual and virtual current and voltage, a d-q synchronous frame is formed. The control vector of single PWM rectifier is
achieved by using power predictive algorithm and instantaneous active and reactive power theory. Furthermore, single pole
modulation strategy is used to generate the required switch pulse of converter in a constant switching frequency. Because
there is no current loop in control strategy, the strategy has a lot of excellent characteristics, such as easy designing, strong
anti-disturbing, fast responding, etc. Simulation results show the effectiveness of the control strategy.
