    摘要: Example embodiments of the systems and methods of reduction of parasitic losses in a wireless power system disclosed herein provide a practical means of accurately estimating parasitic losses in a wireless power transfer system irrespective of coupling. Such systems and methods may be used to generate an equation which predicts parasitic losses in a wireless power system. In an offset case, in which the transmitter and receiver are not directly coupled, losses associated with the recirculating current in the primary LC tank dominate the loss, and the transmitted power may be better estimated by measuring the power inputs, power outputs, and injected losses in a controlled environment; making a mathematical fit to an equation, which from the various power measurements and injected loss, predicts the expected transmitter losses; and then, in an operational environment, using the equation to predict parasitic losses based on the power inputs, power outputs and expected loss equation.

    摘要: A system for wireless power transfer is provided. The system includes a monitoring function to monitor control parameters and an input source that supplies power to a wireless power transmitter, wherein the wireless power transmitter operates with a wireless power receiver to supply a charging current to a load. A controller can be configured to receive the control parameters from the monitoring function and to control an adjustable operating point for the wireless power transmitter which controls the charging current delivered to the load via the wireless power receiver, wherein the controller commands a maximum power operating point for the wireless power transmitter when the input source is detected at or above a predetermined threshold and commands a reduced power operating point for the wireless power transmitter when the input source to the wireless power transmitter is detected below the predetermined threshold.
