Abstract

This paper presents a proposed forward-flyback converter with the snubber-feedback network for the contactless power supply applications. In order to reduce the component count and volume, the output inductor and transformer are integrated with the proposed magnetic integration technology. Since the contactless power supply has the low conversion efficiency and low load regulation, the snubber-feedback network is applied to overcome these drawbacks. In the snubber-feedback network, an auxiliary winding of the integrated transformer is utilized as both the magnetic-loop voltage feedback and the lossless snubber inductor. A prototype circuit of the 15W forward-flyback power converter is built to verify the performances, such as load regulation, voltage stress on the power switch and efficiency, comparing with conventional one.
