摘要： A circuit for providing a regulated a-c or d-c output voltage from an unregulated a-c input voltage. A series regulating network is disposed between the regulator input and the regulator output to support the difference between the unregulated input voltage and the regulated output voltage. A shunt regulating network is connected between the series regulating network and the regulator output to generate a plurality of regulating waves which, together with the input voltage, control the current through and voltage across the series regulating network. Output voltage sensing circuitry controls the phase angle between the input voltage and the regulating waves, as required, to establish and maintain the regulated output voltage.

摘要： A measuring circuit for indicating the magnitude of d-c current flow through an associated circuit or conductor while maintaining electrical isolation therefrom. The measuring circuit includes a voltage generating circuit for generating first and second chopped d-c voltages and a magnetic amplifier comprising first and second cores, first and second gate windings, a control winding and first and second input or command windings. The current to be measured is passed through the command winding to control the current which the voltage generating circuit applies to the control winding through the gate windings. The measuring circuit exhibits a plurality of equilibrium conditions in each of which the magnitude of the control current flow is determined by the magnitude of the input current, thus causing the control current flow to be a continuous d-c output indication of d-c input current.

摘要： A circuit for providing a regulated a-c or d-c output voltage from an unregulated a-c input voltage. A series regulating network is disposed between the regulator input and the regulator output to support the difference between the unreglated input voltage and the regulated output voltage. A shunt regulating network is connected in shunt with the series regulating network to generate a plurality of regulating waves which, together with the input voltage, control the current through and voltage across the series regulating network. Output voltage sensing circuitry controls the phase angle between the input voltage and the regulating waves, as required, to establish and maintain the regulated output voltage.

摘要： A control circuit for eliminating the effect of changes in the frequency of an a-c input voltage on a regulated output voltage in voltage regulator circuits utilizing variable frequency regulating waves. A phase-lock loop controls the frequency of a first, reference oscillator in accordance with the frequency of the a-c input voltage to provide a frequency error signal proportional to the difference between the actual frequency of the input voltage and the nominal frequency of that voltage. The frequency error signal is applied to a second, control oscillator which is not part of the phase-lock loop. This allows the control oscillator to follow input voltage frequency variations without being locked in phase to the input voltage and thus allows the control oscillator to be controlled in accordance with the magnitude as well as the frequency of the a-c input voltage.
