Description

technical field [0001] The invention relates to a wireless power transmission inverter source based on a resonant dc-dc converter, belonging to the technical field of electric vehicle wireless power transmission. Background technique [0002] At present, there are two bottlenecks in the development of electric vehicles: one is the battery problem on the car-from the perspective of recent technology, there are many problems such as volume, weight, price, material, safety, charging speed, and lifespan. The cycle process of production and use is a process of high pollution, resource consumption, and damage to the ecological environment. These characteristics bring difficulties to the industrialization of electric vehicles; Density, power density, etc.), the battery charging time is long and the cruising range is short, and a large number of high-frequency occupied charging or battery replacement facilities are required, which brings great difficulties to municipal construction....
