Abstract

The invention discloses an electric field coupled mobile power supply system for rail transit. The electric field coupled mobile power supply system includes a transmitting part, a receiving part and an energy transmission mechanism. The transmitting part mainly consists of a DC power supply, a high-frequency inverter circuit and a primary compensation network. The receiving part mainly consists of a secondary compensation network, a rectification and filter circuit and a resistive load. The energy transmission mechanism consists of an emitting electrode plate and a receiving electrode plate, and is connected between the transmitting part and the receiving part. The electric field coupled mobile power supply system achieves electric field coupled mobile power supply by moving the receiving electrode plate, improves flexibility, reduces the area and the occupation space of the electrode plates, reduces the reactive power through the reasonable configuration of the transmitting part and receiving part parameters, improves transmission efficiency and transmission power, and is stable.

Description

technical field [0001] The invention relates to an electric field coupled mobile power supply system for rail transit, and belongs to the technical field of wireless power transmission. Background technique [0002] It has been nearly a century since Nikola Tesla proposed the concept of wireless power transmission in the 1990s. Among them, the more in-depth study of wireless power transmission is electromagnetic coupling wireless power transfer (IPT) technology, IPT technology It is based on electromagnetic coupling to realize wireless power transmission. [0003] The traditional wireless power transmission method based on high-frequency electromagnetic coupling will be shielded by some metal conductors with low resistivity in the environment, which will cause large eddy current losses, and will also reduce the transmission capacity and transmission efficiency of the system. Therefore, the application of wireless power transmission methods based on electromagnetic coupling ...
