Abstract
A wireless power transmitter can include an inverter that receives a DC input and generates an AC output to drive a wireless power transmit coil coupled to an output of the inverter as well as voltage and current sensors that measure the DC input. The wireless power transmitter can further include a power management accumulator including hardware that receives voltage and current samples from the voltage and current sensors and multiplies corresponding voltage and current samples to produce power samples and memory locations that store corresponding voltage, current, and power samples. The wireless power transmitter can still further include a programmable controller that controls switching devices of the inverter responsive at least in part to the voltage, current and power samples stored in the memory locations of the power management accumulator.
