Title (EN) HIGH FREQUENCY MULTI-LEVEL RECTIFICATION
(FR) REDRESSEMENT MULTI-NIVEAU HAUTE FRÉQUENCE
Abstract:
(EN) 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. A control signal generation circuit receives the multi-level control waveform and generates control signals corresponding to levels of the multi-level control waveform. A synchronous rectifier receives the input waveform and includes a plurality of switches to provide an output voltage generated from the input waveform. The switches are coupled to receive the control signals and the output voltage is a function of the multi-level control waveform.
(FR) La présente invention porte sur un redresseur multi-niveau qui est approprié pour une utilisation à hautes fréquences, y compris dans une plage MHz telle que dans la bande 6,78 MHz utilisée pour le transfert d'énergie sans fil. Pour maintenir la synchronisation appropriée ou une forme d'onde de commutation lors d'un fonctionnement à hautes fréquences, une boucle de rétroaction est utilisée. Le circuit de redressement comprend une circuit générateur de forme d'onde multi-niveau qui génère une forme d'onde de commande multi-niveau à partir de la forme d'onde d'entrée et une indication de son courant. La forme d'onde de commande multi-niveau est maintenue en phase avec la forme d'onde d'entrée. Un circuit de génération de signal de commande reçoit la forme d'onde de commande multi-niveau et génère des signaux de commande correspondant à des niveaux de la forme d'onde de commande multi-niveau. Un redresseur synchrone reçoit la forme d'onde d'entrée et comprend une pluralité de commutateurs pour fournir une tension de sortie générée à partir de la forme d'onde d'entrée. Les commutateurs sont couplés pour recevoir les signaux de commande et la tension de sortie est fonction de la forme d'onde de commande multi-niveau.
