Abstract
A method and apparatus for converting dc power from one voltage to another, in a mHEV includes an input filter, a converter circuit, and an output filter. the circuit is implemented with wide band gap devices, and may be a full bridge, half bridge, or push pull circuit. The size is preferably 120 cc, and the output power is preferably at least 500 W, 1 KW or up to 3 KW. The efficiency is preferably at least 80% or 90%, and the converter operates at a frequency of at least between 20 KHz and 2 MHz.
