Title: Régulation de dérivation numérique pour un récepteur de puissance sans fil
Inventor: CHAN CHI HONG
IPC: H02J50/20
Filed: 2019-05-10
Abstract: La présente invention concerne un récepteur qui est excité par une puissance sans fil provenant d'une antenne à bobine. Un réseau d'adaptation accorde le récepteur à une fréquence de résonance et un pont et un condensateur génèrent une tension de sortie. La tension de sortie est divisée et comparée à une tension de référence. Un contrôleur numérique asynchrone augmente un compte numérique lorsque le résultat de comparaison est correct, mais réduit le compte numérique lorsque le résultat de comparaison est erroné. Un convertisseur numérique/analogique de direction de courant (DAC) dérive un courant à partir de la sortie qui est une fonction du compte numérique. Le contrôleur numérique asynchrone, le comparateur et le DAC n'utilisent pas une horloge système, de sorte que la rétroaction numérique vers le courant de dérivation fonctionne lorsque la tension de sortie cible est atteinte, empêchant une surtension lors de l'attente que l'horloge système démarre une impulsion. Le compte numérique est comparé à un seuil numérique pour récupérer des données à modulation d'amplitude (ASK) transmises.
