Switching Mode Analysis of Wireless Supplying Rail for Electric Vehicles
摘要
Abstract
In the wireless power transmission system for electric vehicle online power supply, when the segmented rail switches fast, the relevant state variables in the system may change drastically and the over-current and over-voltage may bring about great security risks to the system.To solve the problem of large switching stress, large volume of control system and spike voltage caused by dynamic current in the continuous hard switching mode of segmented rail, a switching method of wireless power supply rail based on an energy free oscillation mode is proposed following its realization of soft switching.The trend towards change in the inductor voltage in the hard switching and soft switching mode is analyzed by developing the electromagnetic transient model of the system.The effectiveness of the method is verified by simulation and experiment.关键词
