Abstract
An apparatus (such as a power converter circuit) includes s primary winding, an auxiliary winding, and an over-voltage protection circuit (such as a controller and corresponding one or more circuit components). The primary winding receives an input voltage. The auxiliary winding is magnetically coupled to the primary winding. The primary winding receives energy from the input voltage, the auxiliary winding receives the energy from the primary winding. The over-voltage protection circuit controls conveyance of the energy received from the primary winding through a discharge circuit path to a reference voltage (such as ground). Conveyance of the energy (as received from the auxiliary winding) associated with the input voltage through the discharge circuit path prevents damage to a respective power converter circuit during exposure of the input voltage to a power surge condition such as due to lightning.
