Abstract

Most existing power semi converters and industrial motor drive systems draw non- sinusoidal currents from the supply. Non-sinusoidal currents contain harm harmonics that disturb the power supply, which is important serious concern for reliability. Other equipment that use the same power supply are adversely affected. This paper suggests the operation and performance of a new modified AC-DC converter that allows bi-directional power flow, provides improved power factor, and reduces harmonic magnitude and disturbance to the supply by system. The bi- directional feature allows recovery of regenerative energy of loads, back to the power supply and the converters. The proposed converter has high potential for industrial drives applications, such as electronically controlled traction system, lifts and general industrial motor drive systems can increase overall efficiency and reliability.
