Abstract :
In previous work, a novel design of a 2.5kW 400V-12V 93.2%-efficiency DC/DC converter with a triggering angle tracking synchronous rectifier was proposed for use in an electric vehicle to replace the electric alternator. This paper is focused on the further enhancement of the DC/DC converter to improve the system efficiency and wide-range input/output performance.
