Problems solved by technology
There are many technical route branches in the wireless charging system itself. If the interoperability requirements cannot be met between wireless charging systems with different modules / parameters / topologies, it may cause waste of power resources on the one hand, and may cause safety hazards on the other hand. Therefore, Ensuring the interoperability of various charging systems is one of the key factors for the development and growth of the industry, and it is of great significance to the interoperability evaluation of resonant topologies
[0003] At present, the research on the resonant topology of the wireless charging system is limited to the characteristic analysis and parameter optimization of a specific topology combination, and does not take into account the actual situation of the coexistence of various topology combinations caused by the non-uniform production standards of the manufacturers in the actual promotion and application. , it is impossible to analyze the changes in output characteristics and control strategies when different charging systems interoperate
