Design and Analysis of DC/DC Converter in 42V/14V Automotive Power System

Abstract:

A growing consumption of electrical energy is necessary for automotives. The present voltage level of automotive power system has increased to 42V. 42V/14V dual voltage system is a prefer choice based on consideration of economy and technology now. In the dual voltage system, a DC/DC converter is needed between the two DC buses. The synchronous rectifier Buck converter is chosen for building the 14V/30A output prototype. The design and loss analysis of converter are given. The experimental results are also included.
