用于一对多无线电能传输系统中的选定谐波注入脉冲密度调制

Multifrequency one-to-many wireless power transfer (O2M-WPT) is advantageous for charging various medium- and small-power loads, offering cost-effectiveness, simplicity, and minimal cross-coupling effects. However, inevitable hard switching caused by the multifrequency modulation method may lead to significant switching losses. To reduce the switching losses, a novel selected-interharmonic-injecte...
