access icon free Isolated step-up converter based on flyback converter and charge pumps

In this study, a single switch isolated step-up converter is presented, which is derived from the traditional flyback converter and charge pump concept. The proposed converter possesses an output inductor, so the output current is non-pulsating. Moreover, there are several advantages of the proposed converter over the traditional flyback converter, such as higher voltage conversion ratio with only additional four passive elements, and smaller voltage and current ripples, except the same switch voltage stress. In this study, some experimental results are provided to verify the effectiveness of the proposed converter.
