Patent attributes
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.
