Embodiments disclosed herein may generate and transmit power waves that, as result of their physical waveform characteristics (e.g., frequency, amplitude, phase, gain, direction), converge at a predetermined location in a transmission field to generate a pocket of energy. Receivers associated with an electronic device being powered by the wireless charging system, may extract energy from these pockets of energy and then convert that energy into usable electric power for the electronic device associated with a receiver. The pockets of energy may manifest as a three-dimensional field (e.g., transmission field) where energy may be harvested by a receiver positioned within or nearby the pocket of energy.

DC input energy is converted into DC output voltage by the use of a switched current mode high-voltage power supply. Pulses of input current are switched through a conversion transformer and the energy content of each pulse is converted into the DC output voltage. The time widths of the input current pulses are regulated relative to the DC input and output voltages, the magnitude of the current within each input current pulse, and in relation to maintaining a plurality of different selected operational conditions. The rate at which the input current pulses are converted is changed relative to the level of the DC output voltage.
