Neutral Point Type Buck-Boost Converter Circuit Application for Wireless Energy Transfer

In this paper, a design circuit of neutral point type buck boost has been utilized for wireless transfer energy application. Resonance magnetic field was used as the preferred wireless energy transfer approach due to its ability to generate high efficiency and an increased in distance between the transmitting and receiving coil. The constructed circuit has been found to be able to transmit a DC voltage output to the receiver coil with relatively small ripple voltage output at a limited range of around 15 centimetres.
