Abstract

In accordance with embodiments of the present disclosure, a power supply unit may include one or more stages including an output stage configured to generate a direct-current output voltage at an output of the power supply, an OR-ing metal-oxide-semiconductor field effect transistor (MOSFET) coupled between the output stage and the output, and a controller. The controller may be configured to measure a signal indicative of a voltage associated with the OR-ing MOSFET and determine an estimated output current of the power supply based on the signal.
