一种基于双有源桥的新型单级低器件计数DC-AC变换器

This paper presents a novel single-stage, isolated, and single-phase dc-ac converter topology, suitable for low-medium power-scale solar photovoltaic and fuel-cell applications. The circuit employs two full-bridge cells with floating dc bus capacitors placed on either side of a high-frequency transformer and works on the dual-active-bridge principle. It has advantages of a single-stage power proce...
