Abstract

This paper focuses on modeling, analysis and simulation of a 42V/14V dc/dc converter based architecture. This architecture is considered to be a technically viable solution for automotive dual-voltage power system in passenger cars of the near future. An interleaved dc/dc converter system is chosen for the automotive converter topology due to its advantages regarding filter reduction, dynamic response, and power management. Presented herein, is a model based on one kilowatt interleaved six-phase buck converter designed to operate in a Discontinuous Conduction Mode (DCM). The control strategy of the converter is based on a voltage-mode-controlled Pulse Width Modulation (PWM) with a Proportional-Integral-Derivative (PID). The effectiveness of the interleaved step-down converter is verified through simulation using control-oriented simulator, MatLab/Simulink.
