一种具有双开关控制电容器的无线电能传输系统效率优化研究

This article proposes a novel wireless power transfer (WPT) system with switch-controlled capacitor (SCC) where variable capacitance and efficiency optimization are realized. The optimum asymmetrical voltage cancellation (OAVC) control is applied to realize wide-ranging soft-switching operation for the active bridge converters. The pulsewidth of the active bridge inverter regulates the output volt...
