摘要: A circuit for loading the rectified AC voltage bus in a housekeeping power supply for an electronically controlled load is provided for avoiding large increases in the rectified AC bus voltage upon disconnecting the load. The load circuit includes a current sink, a relatively small energy storage capacitance, and a negative feedback circuit. The current sink includes a resistance coupled to the rectified AC voltage bus for sinking current whenever the semiconductor switch is on. When the semiconductor switch is off, the small capacitance discharges through the resistive voltage divider. When the voltage across the small capacitance decreases to a threshold mean AC rectified voltage bus value, then the negative feedback circuit provides sufficient current to turn the semiconductor switch back on and thus provide approximately the threshold mean AC rectified voltage bus value. Diodes are provided on the AC rectified voltage bus in order to ensure fast feedback and to separate the current sink resistance from the remainder of the housekeeping supply during normal circuit operation.

摘要: A high voltage, fast pulse rise/fall time, and high repetition rate pulse generator solves the high pulse repetition rate limitations associated with RF power amplifiers and gap switch type pulse generators. The pulse generator employs a transmission line architecture and structural techniques that allow for continued high voltage, fast rise/fall time, and high repetition pulse rate operation of the pulse generator without impairment of the pulse generator while exceeding performance characteristics achievable with conventional RF power amplifiers and gap switch type pulse generators.

摘要: A high voltage, high speed, and high repetition rate pulse generator solves the high pulse repetition rate limitations associated with RF power amplifiers. The pulse generator employs resonant techniques to provide current limiting features that allow for continued high voltage, high speed, and high repetition pulse rate operation of the pulse generator without impairment of the pulse generator during both short circuit and open circuit load conditions.
