Abstract

As the source of energy, the transmitter of the magnetic coupling resonant wireless power transfer (WPT) system has a crucial impact on the performance of the system. The traditional H-bridge inverter is subject to many constraints in the application of high-power WPT due to the defects of the topology itself. In order to make up for the above shortcomings, a quasi-Z-source inverter is used as the transmitting end power converter of the WPT system. From the perspective of control strategy, this paper studies the power and efficiency characteristics of the system in the shoot-through control mode, and the optimal efficiency point of the system is solved on the basis of steady-state analysis, which is verified by simulation.
