Abstract:
This article develops a cost-effective and efficient wireless charger with multiple outputs based on the newly proposed H3-bridge inverter, which has the benefits of reduced switch requirements and independent regulation capability. The output power of each channel is regulated by asymmetric duty cycle control. With the help of the auxiliary LC branch, soft switching is ensured in spite of load variations. The sequential logic of driver signals is analyzed in detail to explore independent regulation characteristics. For arbitrary 2n (or 2n+1) outputs, the total number of required switches is only 3n (or 3n+2), and the voltage stress of switches is the input voltage, which can reduce switch requirements. Simulation and experimental results are in good agreement with each other, proving that the proposed wireless charger is a feasible solution for drone swarms.
