Abstract

Systems and methods for controlling inrush electrical currents (e.g., resulting from power-on event, etc.) using a virtual Miller capacitor and a metal-oxide-semiconductor field-effect transistor (MOSFET). In an illustrative, non-limiting embodiment, a method may include receiving alternating current (AC) power and providing the AC power to an electronic circuit, at least in part, via a bulk capacitor coupled to a field-effect transistor (FET), wherein the FET is coupled to a virtual Miller capacitor circuit configured to limit an amount of AC inrush current provided to the bulk capacitor.
