In this paper, three-level PWM rectifier topology based on the dq coordinate system of the mathematical model based on the voltage oriented control strategy, and using space vector modulation. Simulation results demonstrate that the proposed three-level PWM rectifier provides excellent performance both in steady-state and dynamic load variations. Pure sinusoidal waveforms can be achieved in grid currents with a unity power factor.
