ABSTRACT:
A novel switching mode power supply (SMPS), which is capable of substantially reducing the response time of the SMPS for generating a plurality of regulated DC output voltages from an AC input power, comprises a first rectifier for rectifying the AC input power to produce a rectified AC power signal within a predetermined range; a transforming device for generating a plurality of scaled-down AC power signals from the rectified AC power signal; a second rectifier for producing and providing a plurality of regulated DC output voltages from the plurality of scaled-down AC power signals to the plurality of loads through respective load lines connected thereto; and a unit for grounding the rectified AC power signal previously charged in the first rectifier if there occurs a disruption in the supply of the AC input power to the SMPS, to thereby promptly produce the plurality of regulated DC output voltages when the supply of the AC input power is resumed.
