Direct power control of voltage source rectifier

In view of the fact that active power and reactive power have coupling relation, this paper deduces a novel and simple direct power control of three-phase pulse width-modulated rectifier with constant switching frequency using space-vector modulation(SVPWM), which the input active power and reactive power are decoupling controlled in d-q synchronous reference frame. The SVPWM modulation solves the uncertainty harmonic band of current hysteresis control and reduces the harmonic content. Simulation results show that the proposed method has excellent performance for the control system.
