ABSTRACT:
Power supply turn-on and turn-off transients are eliminated in power supplies employing thermionic vacuum tube pass devices and control amplifiers for controlling the output voltage of the power supply by controlling the conductance of the pass tube or tubes. The elimination of turn-on transients is accomplished by cutting off the pass tube and rendering the control amplifier non-responsive for a predetermined time after the power supply is turned on. The turn-off transients are eliminated by quickly restoring the cut-off of the pass tube and the non-responsive rendering means of the control amplifier very quickly after the turn-off instant of the power supply.
