Abstract

A transformer circuit comprising: a first transformer (T1) and a second transformer (T2), wherein a first terminal of the first transformer is connected to a first terminal of the second transformer; and an inductor (L1), Wherein the inductor (L1) is connected between the second terminal of the first transformer and the second terminal of the second transformer.

Description

technical field [0001] Aspects of the present invention relate generally to power conversion devices, and in particular to a resonant DC-DC power converter. Background technique [0002] Resonant DC-DC converters are seen as attractive power conversion solutions because of the many benefits they can provide. The transformer provides galvanic isolation after the resonant tank, which is important for level translation as well as safety. In some applications, galvanic isolation is required for proper operation. Resonant converters also have inherent properties such as soft switching of the semiconductor switches, resulting in high efficiency and low noise. [0003] The development trend of isolated direct current-direct current (DC-DC) converters aims to achieve extremely high efficiency, high power density and low cost. Resonant DC-DC converters are suitable for implementation in power converters due to their inherent ability to implement soft switching (i.e. zero voltage s...
