A dual AC and DC output flyback converter

This paper presents a new flyback converter topology with dual DC and AC outputs. In traditional flyback converters, usually there are multiple secondary windings that can be utilized to construct few additional output ports. This new topology takes advantage of one of additional secondary windings to generate continuous AC voltage, accompanying with the conventional DC output voltage. In this new topology, the DC output follows the traditional configuration while the AC output is achieved by adding an L-C filter to an additional secondary winding. This new dual-output flyback converter integrates a standalone DC/DC converter with DC/AC inverter which helps save space and switching devices. The main purpose of the proposed dual-output flyback converter is to cope with more general applications especially when both DC and AC power are necessary, such as in rural solar-powered standalone systems.
