Outline
The output characteristics of an LCC-S-type magnetically coupled resonant wireless power transfer (WPT) system are quite different under different parameter configurations. Aimed at the characteristic that the load power on launch vehicles varies in a wide range, a steady-state efficiency model of the WPT system between the rocket and ground was established, and a parameter design method for a resonant network with the average power-efficiency product as an optimization objective was proposed for the first time, so as to improve the system's overall output characteristics in the full power range. On this basis, a time-domain model of inverter output current considering high-order harmonics was built to achieve zero voltage switching of the inverter. In view of the influence of resonance parameter disturbance on indexes such as the switching losses of inverter and the voltage gain, a disturbance design method for resonance network was also given. Finally, the rationality of the model and the superiority of the parameter configuration method were verified by simulation results.
