A novel high power factor PWM rectifier with push-pull control for harmonic reduction in industrial areas networks of smart grid

Currently great attention is paid to more efficient use of electrical energy and considerable significance is especially attached to increase the power quality, in particular, by decreasing high harmonics in supply voltage and current. This paper addresses the important issue of power quality management for industrial smart grid; especially how to mitigate harmonic distortion caused by switching frequency of PWM rectifier and proposes a novel topology of Boost rectifier with push-pull control aiming to improve the current profile. To demonstrate the advantages of this new converter, a comparative evaluation with the basic Boost rectifier is performed and simulation results are discussed.
