Abstract

This paper describes a high voltage design using switch mode power supply (SMPS) technique. The intention is to have low risk and high efficient to deal with laser system. At primary stage an input signal of 12 V was provided into a comparator which acts as a switching drive control unit. MOSFET was employed as a switching unit. It drives the given signal into an isolation transformer to step-up into 230 AC voltages. Network comprises of diodes and capacitors used to rectify the output voltage into a smooth DC signal. The performance of the high voltage SMPS circuit is found to be dependent on the input supply current, the input frequency, the negative feedback resistance and the number stages of voltage multipliers.
