Abstract
Methods, systems, and devices for wirelessly providing power to devices using a non-resonant power receiver are disclosed. A transmitter-side inductor may be inductively coupled to a receiver-side inductor. The transmitter-side inductor and one or more transmitter-side matching capacitors may be included in a power transmitter. The receiver-side inductor may be included in a power receiver. The power receiver may not include a receiver-side matching capacitor. Power from the power transmitter may be provided to the power receiver via the inductive coupling between the transmitter-side inductor and the receiver-side inductor. The power receiver may provide a reflected impedance including a real part and an imaginary part to the power transmitter. The transmitter-side matching capacitor(s) may compensate for the imaginary part of the reflected impedance.
