Bidirectional interleaved DC to DC converter utilizing positively coupled filter inductors

摘要

A bidirectional interleaved DC to DC converter comprises positively coupled filter inductors that are coupled to a switching network that receives power from a DC power source, such as a battery. The positively coupled inductors are integrated as a single coupled inductor, which allows the DC to DC converter to convert DC voltage to various voltage levels with reduced voltage ripple, without the need for supplemental filter capacitors that are large and costly.
