Abstract

Cascaded H-Bridge, CHB, is one of the most widely used topologies in medium voltage drive applications. Recently, regenerative capability has been required to several loads such as laminators, downhill conveyors, and mill drives. Therefore, topologies for Active Front End (AFE)-CHB had been proposed and implemented. In this paper, PWM strategy for AFE 5 Level Cascaded H-Bridge is developed. Conventional PWMs, Phase Shift PWM and Level Shift PWM are analyzed in terms of current harmonics, switching loss, loss distribution, DC-link voltages ripple, and balancing DC-link voltages. To overcome the demerits of the conventional PWM methods, in this paper a novel PWM strategy is proposed. Through the proposed PWM method, the switching loss can be evenly distributed between legs, and THD can be reduced to 60% compared with THD of the conventional method.
