DESIGN AND DEVELOPMENT OF CONTROLLED RECTIFIER FOR A PMDC MOTOR

Abstract

This paper presents the design, simulation and development of a symmetrical angle controlled (SAC) and an extinction angle controlled (EAC) rectifier using MOSFETs for driving a PMDC motor. Using these methods, the power factor can be improved and certain lower order harmonics can be reduced or eliminated. Harmonic analysis of the input current for different extinction angles is also done. The paper also discusses the various performance parameters like power factor and displacement factor of the controlled rectifier. Power factor (PF) for extinction angle, firing angle and symmetric angle at different angles are compared.
