Abstract

The invention discloses a chaos control technique based bidirectional non-contact power supply system. The chaos control technique based bidirectional non-contact power supply system comprises a DC power supply U<H>, a full controlled bridge converter, non-contact transformers, a secondary-side converter, a filter circuit, a BOOST circuit, a charging switching device, a vehicle-mounted storage battery U<bat>, a primary-side controller and a secondary-side controller; in a positive transmission state, a mains supply acquires direct current through a power factor correction circuit, the vehicle-mounted storage battery is charged, and a solar cell also charges the vehicle-mounted storage battery; in a reverse transmission state, the solar cell supplies electric energy to a power supply side reversely, the cost is saved, and the volume and the weight are also reduced; in a positive power supply mode, a limit-cycle theory or a Poincare cross section is used for judging whether switching tubes S1 to S6 of the full controlled bridge converter work in soft switching states; in snow and rain days, a plug is not needed, and the safety performance is relatively high; and in a positive charging mode, three non-contact transformers are used, the power transmission range is larger, and the optimal state of the efficiency can exceed 94%.

Description

technical field [0001] The invention relates to the technical field of non-contact power supply and automatic control, in particular to a bidirectional non-contact power supply system based on chaos control technology. Background technique [0002] Under the traditional power supply mode of electric vehicles, its charging management is a labor-intensive task. Before charging, it is necessary to connect the charging pile to the car with a power supply cable. If you forget to connect the power supply cable, it will affect the next trip. Especially in rainy and snowy weather, the plug of the outdoor power supply cable is wet, and there is a risk of electric shock when connecting the power supply cable. [0003] Compared with this, the superiority of non-contact charging technology is obvious. The power supply coil is installed under the ground of the parking space, and the non-contact charging circuit can automatically determine whether to provide power to the power receiving ...
