Then novel circuit structure of bi - directional voltage mode ( based on forward converter ) inverters with high frequency link, are proposed, which is constituted of input cycloconverter, high frequency transformer, output cycloconverter, input and output filter ; the circuit topologies family of this bi - directional voltage mode inverters with high frequency link include six circuit topologies, such as push pull - full wave mode, push pull - full bridge mode, half bridge - full wave mode, half bridge - full bridge mode, full bridge - full wave mode, and full bridge - full bridge mode etc. taking full bridge - full bridge mode circuit as an example, principle of uni - polarity phase shifting controlled bi - directional voltage mode inverters with high frequency link is introduced
