Abstract :
A compact water-cooled high power, high voltage power supply system is described. The system must deliver an output voltage up to 25 kV, and a current up to 4 A to power a klystron amplifier. The amplifier demands very high voltage stability, low output voltage ripple, and low stored energy. The solution presented is based around Lambda´s proven 303 series DC supplies to provide the bulk high voltage power, an advanced controller for high performance operation, and a precision filter/feedback assembly for low ripple and high accuracy. The system has demonstrated ripple of less than 0.015%, stability better than 10 ppm/degC, power factor of 0.92 and efficiency of 90%, with an output stored energy of less that 8J.
