摘要： An improved power supply having a single input stage which operates a plurality of output stages. The input stage includes an isolation transformer or a push-pull drive circuit. This input stage controls a plurality of regulated output stages. The output stages may include either series or shunt regulators, however, at least one of the output stages includes a series regulator. The series regulated output stage includes a center tap transformer having a transistor connected to the center tap. The output voltage or current is sensed and fed back to the base of the transistor to regulate and keep constant the output voltage or current. A pair of rectifiers are connected between the series regulated output stage and the other output stages to provide isolation between the series regulated output stage and the other output stages.

摘要： A constant-voltage power source device for a highly accurate electric circuit, connected to an A.C. power source, capable of minimizing size of the current loop, making the ground line current constant even when the load current varies, and having a high noise elimination ratio as well as a low output impedance.
The device comprises a constant-current circuit (28) connected in series with the load (26), and in parallel therewith a constant-voltage circuit t30) including a control amplifier (44) which controls the current (I c - 1 0 ) flowing therethrough so that sum of this current and the output current (l o ) of the device supplied to the load (26) equals to the output current (l c ) of the constant-current circuit (28).
The device is particularly suitable for an audio video recording/reproducing apparatus or a measuring instrument, and can be used instead of a battery power source which, until now, has been considered to be ideal for such purposes.

摘要： Standard configuration a.c. power transformer core sections are combined with standard configuration solenoid winding sections to provide a saturable core transformer which is arranged to be driven into saturation by applied alternating and direct current energy with the control of variations in flux changes up to saturation exercised by the direct current flow. A center tapped primary winding is arranged on an I-shaped stack of transformer iron laminations for full-wave excitation. A C-shaped stack of laminations is arranged adjacent to the I-shaped stack and separated by an air gap whereby the primary winding also serves as an input filter choke. The core structure is completed by an E-shaped stack of laminations arranged adjacent to the I-shaped stack and separated by another air gap. Two solenoid windings are arranged on the outer legs of the E-shaped stack and connected to a capacitor for resonating the overall ferroresonant transformer circuit arrangement. Secondary windings are also arranged on the outer legs and connected to a rectifying circuit for supplying direct potential to a load. A control winding is arranged on the central leg of the E-shaped stack of laminations. With this arrangement, the control winding is unaffected by variations in the a.c. voltage as they affect the flux changes in the transformer or in the frequency of the a.c. Regulation of the power supply is executed by direct current flow in the control winding. An adjustable resistor connecting the control winding across the output of the rectifier circuit is often all that is required to complete the circuit. In some applications, an amplifying circuit is used to provide a desired gain in the control winding circuitry.

A circuit configuration for applying power to direct current loads includes a plurality of transformer circuits connected in parallel. Each transformer circuit includes a diode bridge rectifier circuit having the input terminals thereof connected across a secondary coil and the output terminals thereof mutually coupled in parallel with the output terminals of all other transformer circuits. Equalizing reactors are connected in series with the secondary coils to compensate for voltage imbalances that may be developed in the respective transformer circuits. A direct current load may be connected across the mutually coupled output terminals of the respective transformer circuits. Alternating current loads are accommodated by a plurality of parallel coupled transformer circuits each including a transformer having a pair of secondary coils.

A diode rectifier is connected in series with each secondary coil and a silicon-controlled rectifier (SCR), associated with each set of secondary coils, is serially connected with an alternating current load.

摘要： A variable impedance circuit comprises a differential current circuit having a diode and a first transistor connected so as to operate differentially with respect to each other, and a current control circuit for controlling current flowing through the differential current circuit, whereby variation of the operative resistance of the differential current circuit causes variation of impedance thereof. The current control circuit comprises a second transistor having a collector connected with the differential connection of the differential current circuit, and an emitter grounded via a resistor, and a third transistor having a base applied with a control voltage and an emitter connected with the emitter of the second transistor. A fourth transistor is also provided having a collector connected to the base of the second transistor, a base connected to the collector of the third transistor and an emitter applied with source voltage independently from the current flowing through the differential current circuit. The current control circuit is connected with the differential current circuit through only the collector of the second transistor to establish a high impedance of the current control circuit as seen by the differential current circuit.

摘要： Methods for operating a control circuit, having a programmable signal characteristic, in a manner so as to gradually vary a D.C. analog output level from an initial value to a final value, as well as for abrupt changes therein, when an isolation-and-rectification network is used to recover a D.C. voltage of programmably controlled amplitude. The methods also provide for a pulsed output condition in a circuit for providing a periodic signal of programmably controlled amplitude. In such a circuit, the output signal amplitude may be controlled by external data signals to values less than, equal to and greater than, the substantially constant amplitude of an oscillator waveform. Both programmable (computer-controlled) and hard-wired circuitry are disclosed for controlling the output signal by the methods of this invention.
