摘要： Circuit arrangements and methods are disclosed for providing means of driving a grounded anode triode X-Ray tube using one isolation transformer, providing both filament power and controllable grid drive without the need for optical isolation devices. Applications. of this design include fast X-Ray imaging such as inspection equipment and systems, which require rapid control of X-Ray intensity. Grounding the anode in X-Ray tube systems is usually done for thermal considerations and therefore requires that the filament and grid to be floating at an extremely large negative potential, usually over 100 kVDC. Isolation transformers are-required to provide power to the filament and grid. In this invention, both AM and FM signals are coupled through one isolation transformer. The AM waveform provides controllable power to heat the filament while the FM signal, adjusted in magnitude by a filter arrangement, rectified and smoothed in waveform, provides power for the grid. This design eliminates the need for an additional grid isolation transformer or optical control of the grid element where active circuitry is prone to failure due to tube arcing.

摘要： Circuit arrangements and methods are disclosed for providing a source of low power DC, direct and isolated from the main AC line. Applications of this circuitry include battery chargers and air ionizers. In this design, a high frequency ferrite transformer 16 is driven by signals created from a bilaterally conducting two state device 12 operating in series with a capacitor 15. Utilizing a bilaterally conducting two state device 12, capacitor 15 is alternately charged positive and negative to a certain voltage level depending on the characteristics of 12. The device 12 will see an increasing voltage across it due to the increasing magnitude of the input AC waveform. When the voltage across 12 reaches the breakover voltage of the device, Vbo, it rapidly changes state from a blocking condition to one of full conduction. When this occurs the stored energy present in the capacitor 15 causes fast rise time pulses rich in high frequency harmonics to be impressed across the primary of the transformer 16 which has been designed with an operating frequency of 20 kHz or greater. A simple rectifier stage on the secondary consisting of 18 will convert the AC pulses generated on the secondary of 16 to the desired DC output voltage where it is filtered with capacitor 19. For high voltage applications, a multi stage, Cockroft Walton voltage multiplier circuit may be utilized on the secondary of 16.

摘要： A high voltage power supply for use in small diameter spaces such as in oil well logging devices includes an AC voltage source which provides an AC voltage to a voltage multiplier circuit that converts the AC voltage to a high DC voltage.

摘要： A high voltage power supply for use in small diameter spaces such as in oil well logging devices includes an AC voltage source which provides an AC voltage to a voltage multiplier circuit that converts the AC voltage to a high DC voltage. A parallel or combination parallel-series multiplication circuit is used, rather than a series multiplication circuit, to reduce the reverse voltage across each semiconductor rectifier in the multiplication circuit. The lower reverse voltage reduces leakage currents allowing such circuits to operate at temperatures over 150 degrees C. A special construction of high voltage capacitors allows the power supply to fit small spaces. A piece of elongate conductive material, such as a metal cylinder, forms a common capacitor electrode and is coated with a high voltage dielectric. Separate individual capacitor electrodes are formed around the common electrode and dielectric.

摘要： A high voltage pulse generator is disclosed. The high voltage pulse generator comprises a pulse generating transformer having a primary coil with a first side and a second side, and a secondary coil with a first side and a second side. A direct current (DC) voltage source connection is at the first side of the primary coil. A first high frequency power driver transistor is coupled between the second side of the primary coil and a ground connection. The first high frequency power driver transistor is configured to operate in an on-mode for a selected time period to charge the primary coil for the selected time period based on a switching frequency of the first high frequency power driver transistor, and switch the first high frequency power driver transistor to an off-mode at the switching frequency to release the charge from the primary coil to the secondary coil. A diode is coupled between the first side of the secondary coil and a pulsed voltage output that is configured to be connected to a high voltage device. The diode configured to direct a flow of charge from the secondary coil to charge a capacitance of the high voltage device to a rising pulse leading edge of a voltage pulse.
