Abstract

Bidirectional DC-DC converters are an essential part of modern power systems, such as electric vehicles and renewable energy. The paper presents a comparative analysis of bidirectional DC-DC converters suitable for high power density application without galvanic isolation. It is based on the comprehensive comparative analysis of conduction losses, voltage stress on semiconductors and passive component size. Continuous conduction mode of three widely used bidirectional topologies (cascaded, two-phase interleaved with and without charge-pump) are analysed. Selected analytically calculated evaluation criteria are compared for a wide range of the output voltage level. The best solution is selected for experimental realization based on GaN transistors.
