ABSTRACT:
An improved power supply capable of driving an external device at relatively high power levels for intermittent periods of time with the power supply driven by relatively low current input power which can vary widely in voltage. The power supply incorporates a step-up switching voltage converter module for increasing the input voltage to a higher value so as to charge an energy storage capacitor to an energy level sufficient to power the external device for said intermittent periods of time at relatively high current. The energy storage device voltage output is regulated by a step-down switching voltage converter module. Control signals sensing the voltage of the energy storage capacitor can be used to control energization and de-energization of the external device.
