Abstract
A control system includes a rectifier bridge including a heat sink having a temperature, and also including an SCR having a gate. The SCR thermally engages the heat sink. A circuit controls the rectifier bridge through the gate of the SCR. An RTD circuit measures the temperature of the heat sink. A circuit disables gating of the SC based upon the temperature of the heat sink.
