Abstract

Systems and methods are described for thermal feedback for power transfer optimization. Aspects include a wireless power-transfer system including a base power-transfer apparatus, a power supply unit, at least one temperature sensor, and a system controller. The base power-transfer apparatus includes a coil configured to generate a magnetic field based on an electric current. The power supply unit includes switching and power electronics configured to drive the electric current in the coil. The temperature sensor(s) are configured to measure a temperature of the base power-transfer apparatus or the power supply unit. The system controller is coupled to the base power-transfer apparatus, the power supply unit, and the temperature sensor(s) and is configured to control operation of at least one of the base power-transfer apparatus or the power supply unit based on the measured temperature to shift losses and dissipate heat in the base power-transfer apparatus or the power supply unit.
