PURPOSE: A non-power failure power supply system is provided to reduce an overload of passive equipments by distributing peak power use time slots by automatically providing power stored in a non-power failure power device unit to a load device when entering a set time slot. CONSTITUTION: An input filter unit(110) filters an electric noise of commercial power(1). A non-power failure power device unit(120) is connected with a first switch(SW1) in series. A variable impedance unit(130) is connected with the non-power failure power device unit and the first switch in parallel. The variable impedance unit is controlled with the same impedance as the non-power failure power device unit's by a control unit(140). A detecting unit(160) detects the amount of currents outputted from the variable impedance unit.
