SYSTEM AND METHOD TO MAINTAIN POWER SUPPLY OF LOAD

摘要

FIELD: electricity.SUBSTANCE: invention relates to electrical engineering. The power supply system and method contain a power supply source; one or more loads supplied from the power supply source; boosting voltage circuit in order to increase voltage at input from the primary power supply source; a capacitor to accumulate voltage from the boosting voltage circuit; and voltage stepping-down circuit to decrease voltage from the capacitor and to deliver lower voltage to one or more loads when the power supply source is unavailable.EFFECT: potential reduction of the required capacitance for the accumulating capacitor.19 cl, 2 dwg
