Abstract
A method of controlling a power supply using software comprises setting a nominal output level through a waveform controlled by a micro-controller. The method identifies when a device is fully charged, and moves to a keep-alive mode, in which the output level is decreased below the nominal output level when the device is fully charged. The method further provides a failsafe to move the system to the keep-alive mode when the micro-controller is halted, crashed, in an error state.
