Abstract

Advanced vehicles, i.e. electric and hybrid cars, with the high-voltage battery pack as the primary power source, require conversion of the battery DC voltage into the low onboard DC voltage. Safe operation of the system can be achieved with galvanic isolation of the high-voltage source and onboard consumers. This article presents the main circuit solutions for car DC voltage conversion and considers some of the issues related to the design of the isolated DC-DC converters, as well as a method and key principles for calculating the converter characteristics.
