Abstract A capacitive power transfer system can include a power transmitter having one or more primary side filter components, a communications modulator, and transmitter capacitive couplers; and a power receiver having receiver capacitive couplers capacitively coupled to the transmitter capacitive couplers, one or more secondary side filter components, and a communication demodulator. The one or more primary side filter components and the one or more secondary side filter components can be selected to provide power amplifier operation at a power delivery frequency and act as a stable gain high pass filter above a communications cutoff frequency that is higher than the power delivery frequency. Un système de transfert d'énergie capacitif peut comprendre un émetteur d'énergie ayant un ou plusieurs composants de filtre côté primaire, un modulateur de communication et des coupleurs capacitifs d'émetteur; et un récepteur d'énergie ayant des coupleurs capacitifs de récepteur couplés de manière capacitive aux coupleurs capacitifs d'émetteur, un ou plusieurs composants de filtre côté secondaire, et un démodulateur de communication. Le ou les composants de filtre côté primaire et le ou les composants de filtre côté secondaire peuvent être sélectionnés pour assurer un fonctionnement en amplificateur de puissance à une fréquence de distribution d'énergie et faire office de filtre passe-haut à gain stable au-dessus d'une fréquence de coupure de communication qui est supérieure à la fréquence de distribution d'énergie.
