Implementation of a Resonant Converter with Topology Morphing to Achieve Bidirectional Power Flow

A DC converter with the benefits of reverse power capability, less switching loss and wide voltage operation is presented implemented for input applications such as fuel cell energy, photovoltaic (PV) system wind power. Two full bridge resonant circuits are used in to achieve bidirectional flow capability reduce losses on active devices. To overcome variation problem energy PV solar panel, topology morphing between half circuit adopted primary side obtain low (or high) gain under a high low) condition. Therefore, stable controlled at load by using variable frequency modulation. The studied hybrid CLLC tested 1 kW prototype performance verified confirmed experiments.
