Design and Simulation of PFC Rectifier for DC Motor Drive

Abstract

In order to reduce the cost, many single- stage PFC converters, which integrate the PFC stage with the
DC/DC stage into a single stage, have been proposed recently. The main idea is that the PFC stage and DC/DC stage
share a common switch so that one main switch and its controller can be saved. This paper presents the design and
implementation of a three-phase high power factor mains interface concept appropriate for many power electronic
applications such as electric vehicle battery charging, supplies for dc power distribution systems in telecommunication,
variable-speed ac drives, dc motor drives ,future more electric aircraft and high power lighting systems. The circuit
topology comprises a power factor correction rectifier which is of buck-type circuit built by the combination of an active
third-harmonic injection rectifier and a series-connected dc–dc buck-type chopper. The characteristics of this rectifier
topology, including the, modulation strategy, principles of operation, suitable control structure, and dimension
equations, are described in this paper. The practicality of the presented converter for buck-type rectifier applications is
verified by means of a constructed through Matlab/Simulink. the implemented system has been compared to another
remarkable buck-type Swiss Rectifier. Finally DC-Motor is connected to the system and observes the motor is settling
down to Study State at 0.5 Seconds.
