DESENSITIZATION OF DC POWER SUPPLIES TO MOMENTARY AC POWER FLUCTUATIONS

Abstract

Lightning storms and faults cause momentary voltage dips and momentary power interruptions in the AC power. These brief disturbances reach electronic equipment through fluctuations in the output voltages of DC power supplies. The report describes methods to desensitize DC power supplies to momentary AC power source perturbations. DC output voltage sustaining characteristics for basic transistors and silicon-controlled rectifier power supply circuits are discussed and performance data presented. By the use of an auxiliary energy reservoir circuit, the DC output of a power supply was maintained at its nominally rated value when an AC power interruption of 167 msec occurred.
