Abstract: A constant voltage power supply employs a circuit in which the average voltage over a specified period of time is maintained constant by a circuit for charging a voltage storage means with width modulated pulses applied several times during each specified period whereby to charge the storage means above the desired average level and terminating charging until the voltage falls below the specified level. The period of time over which the voltage is averaged is a function of the thermal inertia of a load to be driven. The average voltage is employed as the energizing circuit to a high frequency oscillator, and driver stages supplying the output of the oscillator to an output stage of a power supply whereby the energizing voltage of the stages and thus the dissipation of energy therein does not exceed that required to feed the lead at its then current energy requirements.

Abstract: In a transformer power supply, a full wave rectifier is series connected in circuit with the primary winding of the transformer such that the current flowing through the primary winding of the transformer flows in series through the input of the full wave rectifier. An inductive load is connected across the output terminals of the full wave rectifier such that the rectified output current flows through the inductive load. The full wave rectifier preferably uses silicon controlled rectifiers which are phase triggered in such a manner so as to control their conduction angles so as to control the power flow from the source to the load connected to the secondary of the transformer. The inductance of the load for the rectifier preferably exceeds the critical inductance so as to minimize ripples in the secondary of the transformer. This type of power supply circuit is particularly useful for supplying power to an electron gun which is subject to arcing. The inductive load for the rectifier reduces the transient voltages impressed on the transformer resulting from SCR phase control and also minimizes AC voltage drop across the inductive load while providing transient current limiting as may be encountered by arcing of the electron gun.

Abstract: A method of digital control of m-phase thyristor-pulse converters, in which the duration of the conductive state of the thyristors of each phase of an m-phase thyristor-pulse converter is changed by sending time-shifted and time-constant pulse trains successively from each control channel to the thyristors of respective phases with simultaneous shift of the onset of operation of the thyristors of each phase by (1/m) period of switching the thyristors. Successive connection of each control channel to a respective phase is effected upon achieving the maximum value of the control zone of each control channel. The apparatus for carrying out the proposed method includes a master oscillator connected to a clock counter whose outputs are connected to the inputs of a decoder for decoding the time-constant pulse trains and to the logic inputs of "m" decoders for decoding the time-shifted pulse trains. The data inputs of each of the "m" decoders are connected to the data outputs of a bidirectional counter connected to a control unit, while the ouput of each of the "m" decoders is connected to one of the "m" data inputs of a matching unit whose control inputs are connected to the control outputs of the bidirectional counter. The matching unit includes "m" groups of AND gates, each group comprising "m" AND gates; the output of each AND gate of the 1-th group is connected to the 1-th control output of the bidirectional counter, while the other input of the 1-th AND gate of each group is connected to the output of the decoder for decoding the 1-th time-shifted pulse train, where 1=1,2, . . . m and m is the number of phases of the polyphase thyristor-pulse d-c converter.

Abstract: A digital firing control circuit is disclosed for controlling the generation of firing pulses for the eight controlled rectifiers (thyristors) in a bridge power converter in five distinct operating modes as well as effecting a smooth continuous transition between modes. The circuit compares and combines a plurality of locally generated time related waveforms according to a predetermined control algorithm in response to an applied analog command voltage to control the d.c. output voltage as well as providing certain protection functions such as end stops or inversion limits. The locally generated time related waveforms comprise sets of square voltage signals generated in accordance with selected cross-overs of the line voltages of the a.c. sources as well as the cross-overs of six firing reference ramp voltage signals separated from each other by 60.degree. and extending 240 electrical degrees. One particular mode of interest exists at relatively low voltage levels wherein the phase leg thyristors are respectively rendered conductive for a period of 60.degree. in the range of firing angles from 90.degree. to 120.degree. with the neutral leg thyristors being fired 60.degree. after the phase thyristor firing, or at a firing angle of 150.degree. to 180.degree. .

Abstract: The input terminals of a PWM converter are connected to the a-c power supply via a reactor. A capacitor C as well as a load 11 are connected to the d-c output terminals of the PWM converter. An apparent phase of the power supply voltage E is shifted depending upon the difference between a d-c voltage detected across both terminals of the capacitor and a set voltage, and a control signal for the PWM converter is prepared, with the shifted voltage as a reference. When the detected voltage is greater than the set voltage, the PWM converter is so controlled as to be operated with a lagging power factor, and the a-c voltage at the input terminals of the PWM converter becomes smaller than the power supply voltage. Accordingly, the d-c voltage can be maintained at a value smaller than the set voltage.

Abstract: A power supply circuit having a higher power factor and decreased current crest factor. The circuit preferably comprises an input circuit for receiving an input AC voltage and rectifying this voltage and an output circuit for providing a DC output voltage. A pulse-width-modulation circuit intercouples between the input and output circuits and includes a controlled circuit adapted to pass input AC current in pulse-wide increments with the pulse-width varying in inverse proportion to the AC voltage. In this manner, when the instantaneous AC voltage is low, the pulse widths are wider and conversely when the voltage is high, the pulse widths are narrower. In one version of the invention, the pulse width modulation is carried out by a programmed variable ratio transformer. In one preferred embodiment of the present invention, the current spreading circuit is of a quasi cosecant type while in another preferred embodiment of the invention, there is a combination of pulse-width-modulation with a typical input filter circuit including an OR circuit at the output to provide the necessary combining.
