Abstract: An electrical connector assembly includes: a male connector, provided with a conductive shell; a first substrate, accommodated in the conductive shell and used to transmit receiving signals; a second substrate, accommodated in the conductive shell and used to transmit sending signals; a shielding sheet, located between the first substrate and the second substrate; a female connector, provided with a first conductive body and a second conductive body; a plurality of first signal terminals, accommodated in the first conductive body and used to transmit receiving signals; and a plurality of second signal terminals, accommodated in the second conductive body and used to transmit sending signals. The first signal terminals and the first substrate are electrically contacted to each other. The second signal terminals and the second substrate are electrically contacted to each other. The first conductive body and/or the second conductive body are used to lap joint with the shielding sheet.

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.
