Cascade reverse double Γ-LC resonant power converter

Resonant power converter (RPC) is the heart of many systems and equipment. Many topologies shown in open literature are the series resonant converters (SRC) and parallel resonant converters (PRC) that consist of two or/and three energy storage elements. However, they have a lot of limitations, which can be overcome by adding a fourth energy storage element. This paper introduces a cascade reverse double Γ-LC RPC, which has very smooth waveforms of output voltage and current, and very low total harmonic distortion (THD) value. It effectively reduces the power losses and largely increases the power transfer efficiency. Testing results verified our design and analysis.
