Abstract

The invention discloses a magnetically coupled resonance type electric car wireless charging system. The magnetically coupled resonance type electric car wireless charging system comprises a chargingpile part and an electric car part, the charging pile part comprises an AC-DC converter, a Buck circuit, a high-frequency inverter circuit, a main controller and a primary compensation circuit, the electric car part comprises a battery pack, a secondary side controller, a power regulation module, a rectifier filter module and a secondary side compensation circuit, and the input end of the AC-DC converter are connected with a power supply end. The magnetically coupled resonance type electric car wireless charging system adopts a non-contact resonance conversion technology to optimize parametersof the coil coupling coefficient, and thus the purposes of enhancing coupling and improving the charging efficiency are achieved.

Description

technical field [0001] The invention relates to a wireless charging system, in particular to a magnetic coupling resonance type electric vehicle wireless charging system. Background technique [0002] Due to its unique advantages, wireless charging is expected to become the conventional charging method for electric vehicles, robots and other equipment in the future. At this stage, non-contact charging has not only been applied to low-power products that work in close quarters, such as mobile phones and sensors, but also can be used for charging. Wirelessly power tiny implantable medical devices such as pacemakers and embedded neurotransmitters. When wireless charging technology is applied to the non-contact charging system of new energy vehicles, it will not only improve the convenience, safety and versatility of charging [5] , and reduce the operating costs of charging piles and power stations, which is conducive to promoting the rapid development of the new energy vehicle...
