20210159732 | REACTIVE POWER REGULATION OF WIRELESS POWER TRANSFER NETWORK - A wireless power transmission method of control where an electrical parameter of a resonant circuit, which is part of a transmitter antenna tuning and coupling unit, determines in some part the regulation current level target or power level target of the resonant circuit. By using an electrical parameter of a resonant circuit to establish a current or power regulation level of the resonant circuit, a maximum limitation is established for the electrical current and voltage of the antenna tuning and coupling unit in order to operate the electrical elements within safe design limits. Additionally, energy is managed entering the transmitter antenna tuning and coupling unit for variable load at the receiver. | 2021-05-27 |
