Abstract

An apparatus (such as a power converter circuit) includes s primary winding, an auxiliary winding, and an over-load protection circuit (such as a controller and corresponding one or more circuit components). A secondary winding is magnetically coupled to the primary winding and the second auxiliary winding. The controller controls input current through the primary winding of the transformer to produce an output voltage from the secondary winding. The controller monitors a magnitude of an auxiliary voltage received from the auxiliary winding magnetically coupled to the primary winding. The controller detects an overload condition associated with the output voltage based on the magnitude of the auxiliary voltage received from the auxiliary winding. In response to detecting the overload condition, the controller can be configured to reduce a magnitude of the input current inputted to the primary winding, preventing damage to the power converter circuit and corresponding circuitry.
