In order to improve autonomous underwater vehicle's activity and expand the scope of its navigation, contactless power transmission technology has been widely spread in recent years. The contactless power transmission system is loosely coupled coupler connection, making the transmission efficiency of the system is greatly reduced. In this paper, we use soft-switching circuit to improve the transmission efficiency of system. By investigating the passive lossless snubber circuit with non-minimum voltage stress, this paper designs a novel passive lossless snubber circuit based on Buck converter. The experiment results show that the designed circuit can reduce the switching losses effectively and return the energy stored in the buffering process to power supply.
Keywords:Contactless Power Transmission System;Soft-switching Circuit;non-minimum switch voltage stress circuit
