Patent number: 9960608Abstract: A multi-level rectifier is presented that is suitable for use at high frequencies, including into MHz range such as in the 6.78 MHz band used for wireless power transfer. To maintain the proper timing or switching waveform when operating at high frequencies, a feedback loop is used. The rectification circuit includes a multi-level waveform generator circuit that generates a multi-level control waveform from the input waveform and an indication of its current. The multi-level control waveform is maintained in phase with the input waveform.
