Research on Soft-switching Circuit of Contactless Power Transmission System in Autonomous Underwater Vehicle
首发时间:2012-09-21
Abstract: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.

自主水下航行器非接触电能传输系统中软开关电路的研究
摘要:为了提高自主水下航行器的续航能力,增加活动范围,无线能量传输技术近年来得到了广泛应用。非接触能量传输系统利用松耦合变压器进行连接,使得传输效率大幅度减小。所以本文提出一种用于非接触能量传输中的软开关电路,用于提高系统的传输效率。本文设计了一种新型的非最小电压应力无源无损软开关电路,以Buck变换器为基础进行研究。实验结果表明文中提出的软开关电路能够有效的减小开关损耗,提高系统的传输效率
