Abstract:
1. A power converter system, comprising: a step-down device adapted to receive source AC power at a first voltage level and configured, upon receipt of the source AC power, to supply stepped-down AC power at a second voltage level that is less than the first voltage level; a low power regulator circuit coupled to receive the stepped-down AC power from the step-down device and operable, upon receipt thereof, to supply relatively low voltage, regulated DC power; a low power control circuit coupled to receive a command signal, and power that is supplied by the low power regulator circuit, the low power control circuit operable, upon receipt of the command signal, to supply an enable signal; and a high power regulator circuit adapted to receive the source AC power and coupled to receive the enable signal from the low power control circuit, the high power regulator configured, upon receipt of the enable signal, to convert the source AC power to regulated DC power at a third voltage level that is less than the first voltage level and greater than the second voltage level.
