Abstract

The invention discloses a non-contact rail transit power supply system and method. The system comprises a plurality of power supply subsection intervals; each power supply subsection interval comprises a power supply subsection area main controller, a receiving coil, a receiving device, and N sets of power supply equipment connected in parallel, wherein N is the number of sections of a train; eachset of power supply equipment comprises a high-frequency inverter, a primary side compensation circuit, a first high-speed switch, a second high-speed switch, a first transmitting coil and a second transmitting coil. According to the non-contact rail transit power supply system, power supply section area main controller can accurately determine the position of the train according to the output current and the output phase of the high-frequency inverter, and achieves non-contact power supply to the rail transit train according to the determined position of the train.

Description

technical field [0001] The invention relates to the technical field of rail transit power supply, in particular to a non-contact rail transit power supply system and method. Background technique [0002] At present, with the rapid development of semiconductor power devices, the application range of non-contact power supply technology is constantly expanding, and is gradually replacing traditional power supply methods with its advantages of high efficiency, convenience, environmental protection, and economy. [0003] When the non-contact power supply technology is applied to the rail transit power supply system, most of the photoelectric sensors are used for position detection. However, when the traditional photoelectric sensor is used to judge the position, it will cause a wrong position judgment due to bad weather, obstacles, etc., so it is easy to As a result, the train power supply system cannot operate normally. [0004] Therefore, how to effectively realize the contact...
