Abstract :
The paper analyses the disadvantage of conventional input voltage space vector strategy based on direct power control (DPC) of three-phase boost type PWM rectifiers, and proposes a new scheme which dividing the input voltage space into nonzero twelve space vectors with a new switching table. Simulation results in different load verify that the scheme can more availably decrease the control error of reactive power and current waveform´s harmonics, and improve properties of dynamic and static state.
