Abstract:
A power system has a power converter adapted for converting a first input voltage at an input thereof to a first output voltage at an output thereof, and a hold-up time extension circuit comprising a step-up stage and a step-down stage coupled to each other via a first energy-storage capacitor, where an input of the step-up stage is coupled to the input of the power converter, an output of the step-up stage is coupled to an input of the step-down stage, and an output of the step-down stage is coupled to the input of the power converter. The step-up stage is adapted for converting the first input voltage of the power converter to a second output voltage, and the step-down stage is adapted for converting the second output voltage of the step-up stage to the input voltage of the power converter.
