Abstract
In at least one embodiment there is provided a method for managing bulk capacitance of a power supply system. The method includes precharging first and second bulk capacitors of the power supply system to approximately a first output voltage level and a second output voltage level, respectively; receiving a first command signal to generate, by the power supply, the first output voltage level; coupling the first bulk capacitance to load circuitry coupled to the power supply; receiving a second command signal to generate, by the power supply, the second output voltage level; and coupling the second bulk capacitance to the load circuitry coupled to the power supply.
