摘要： A direct voltage transformer device embodying a DC-AC inverter means at the input side thereof for delivering a square wave voltage output, said inverter means including a regulating circuit means incorporating an adjustment element for changing the pulse width of said square wave voltage output for maintaining constant the secondary direct voltage. A half-wave rectifier circuit arrangement receives the square wave voltage output of the inverter means. This half-wave rectifier circuit arrangement comprises an input transformer means constituted by a primary winding and a secondary winding, a first rectifier element electrically coupled to one terminal of said secondary winding, a subsequently coupled filter coil and capacitor filter. There is also provided a further transformer means having primary winding means and secondary winding means, wherein said primary winding means constitutes said filter coil. Additional rectifier circuit means are electrically coupled with said secondary winding means of said further transformer means, said additional rectifier circuit means conducting during the blocking periods of said first rectifier element coupled with said one terminal of said secondary winding of said input transformer. A second rectifier element is coupled between the junction point of said first rectifier element and said filter coil and the other terminal of said secondary winding of said input transformer means, this second rectifier element blocking during the conductive periods of said first rectifier element.

摘要： A DC to DC converter embodying transistors in compound-connected multiple arrays, providing high current gain with special means for reducing switching losses, the arrays being driven in an alternate switching action to apply power pulses to an time-delay transformer under control of pulse-forming and gating subcircuits utilizing multivibrator means controlled by an inverter to produce sets of voltage-conformed gating pulses in such a manner that the power pulses are thereby shaped for substantially constant energy content as the result of automatically adjusting the duration of the pulses in inverse proportion to the instantaneous voltage of the DC source to produce a substantially constant output voltage between predetermined limits of source voltage for a given load condition. A low-loss reflex outputvoltage regulating means may additionally modify the pulse shape in response to load variations. A dual-function isolation and time-delay input circuit prevents feedback into the source and also cooperates with start-stop protective means to guard the power transistors against destructive current surges during turnon and turnoff of the converter.

摘要： A high-voltage power supply has a controlled output oscillator operated from a low-voltage DC source. The output voltage of the oscillator is increased by a voltage multiplier. A series circuit comprising a high ohmic resistor, a transistor device and an adjustable low ohmic resistor is connected in parallel with the oscillator output, and the transistor impedance is varied to maintain a constant current in the parallel path. The voltage developed at the transistor for maintaining a constant current is then used to control the oscillator in order to maintain constant output voltage.
