Abstract:
A capacitive contactless powering system (100) comprises a pair of receiver electrodes (141, 142) connected to a load (150) through a first inductor (160), wherein the first inductor is coupled to the load to resonate the system; a pair of transmitter electrodes (121, 122) connected to a driver (110); an insulating layer (130) having a first side and a second side opposite each other, wherein the pair of transmitter electrodes are coupled to the first side of the insulating layer and the pair of receiver electrodes are decoupled from the second side of the insulating layer, such that a capacitive impedance is formed between the pair of transmitter electrodes and the pair of receiver electrodes, wherein a power signal generated by the driver is wirelessly transferred from the pair of transmitter electrodes to the pair of receiver electrodes to power the load when a frequency of the power signal matches a series-resonance frequency of the first inductor and the capacitive impedance.
