Abstract
Power electronics based power systems are being increasingly used in the transportation systems such as land, sea/undersea, air, and space vehicles due to their advantages in efficiency, performance, flexibility, and power density. In order to have superior performance, the rectifier-converter systems need to be rigorously regulated. The DC power supply is an important aspect for the automotive industries because of its use for a wide range of loads and is mandatory for charging the battery. However, DC power supplies experience many problems such as poor power factor, high input current harmonics distortion and un-controlled DC voltage. In this paper, an integrated control scheme is proposed for regulated DC power supply with high power quality for automotive applications. The proposed control scheme consists of two nested loops with a feedback of DC voltage and input current and a feed forward of the output power supply. An improved input power factor correction with a low input current total harmonics distortion has been used to model the power system using a combined control system. The proposed control scheme achieves nearly unity power factor with a minimum input current total harmonics distortion and able to supply regulated DC voltage with high power quality.
