Abstract

Under normal conditions of operation, E1 is the steady state A. C. input. Switch SW causes ER1 to be supplied to the series regulator. E2 is twice the value of E1. Voltage transients are detected by the amplifier which in turn operates SW.

Transient Buffer System for Digital Computer Power Supplies

Under normal conditions of operation, E1 is the steady state A. C. input. Switch SW causes ER1 to be supplied to the series regulator. E2 is twice the value of E1.

Voltage transients are detected by the amplifier which in turn operates SW.

The series regulator is designed to operate successfully down to a specific percent undervoltage, for example 50%. Should E1 drop below 50% of the normal input, the amplifier switches ER2 to the series regulator input. When E1 is one half its normal value, E2 is equal to the normal value of E1. As E1 rises above 50% of its normal value, the amplifier switches ER2 out and ER1 in.
