1 . INTRODUCTION
Higher voltage from a lower one can be obtained using a step- up transformer(Kasatkin & Nemtsov 1986). Here such a circuit is analysed and quantitative relations between various parameters are derived for the sake of easy tailoring of the circuit as per ones requirement. It consists of a pulsatile current drive circuit for the primary of the transformer using a transistor switch and a rectangular wave oscillator. The output of the secondary which provides the high voltage pulses can be connected to a bridge rectifier and a capacitor filter as shown in Figure 1 or further enhancement in voltage can be achieved by using a voltage multiplier network(Cockcroft-Walton multiplier).
