A power module includes a switch portion (214) operative to switch an alternating current (A/C) voltage, a rectifier portion (208) operative to receive the switched A/C voltage, rectify the switched A/C voltage, and output a direct current (D/C) voltage, a power control module (206) operative to receive the D/C voltage and to charge a voltage storage device, and a controller portion (212), configured to be powered by the D/C voltage from the voltage storage device, operative to receive an external control signal and control a state of the switch portion (214). |
