  • Boost-forward-flyback high gain converter
    Patent number: 8368362
    Abstract: A boost-forward-flyback convertor has a boost converting circuit, a forward converting circuit, a flyback converting circuit and a transformer. The boost converting circuit, the forward converting circuit and the flyback converting circuit are coupled by using elements of the boost and forward converting circuits to form the transformer. The boost-forward-flyback convertor combines benefits of conventional boost, forward and flyback convertors, specifically combines active clamping and lower power pressure to the element from the boost convertor, increases gain ratio by using the forward convertor and provides output to the load during a switch OFF-state from the combination of the flyback and boost converting circuit. The boost-forward-flyback convertor combines benefits of conventional boost, forward and flyback convertors and not only has very high gain, high converting efficiency and lower power loading for devices, but also is simple, cost less, easy to use and has a small volume.
