Abstract :
Nuclear experiments need a precise and accurate high voltage power supply for their transducers to maintain their performance. The basic switching power supply unit, which is used for this purpose, consists of a DC-to-DC power converter, an error amplifier and a power amplifier. In this paper, a PC software simulation tool is employed to analyse the performance of two different schemes for the DC-to-DC power converter regulation based on a PWM chip. From simulation results, the first scheme is found to recover faster than the second after load application and the second scheme suffers from slight increase of overshoot in the transient response. The first scheme has been constructed practically in a circuit for a 0-2 kV/1 mA supply and its performance agrees well with simulation results
