Abstract :
A Cockcroft–Walton high-voltage power supply with high stability and low-ripple voltage has been developed. This power supply has been operated in a ns pulse neutron generator. The maximum non-load voltage is 600 kV while the working voltage and load current are 550 kV and 15 mA, respectively. The tested results indicate that when the power supply is operated at 300 kV, 6.7 mA and the input voltage varies ±10%, the long-term stability of the output voltage is S = ( 0.300 – 1.006 ) × 1 0 - 3 . The ripple voltage is δ U P - P = 6.2 V at 300 kV, 6.8–8.3 mA and the ratio of δUP−P to the output voltage VH is δ U P - P / V H = 2.1 × 1 0 - 5 .
