    Abstract: Design, development and simulation of a<br>
microcontroller based High Voltage Power Supply<br>
(HVPS) have been presented in this study. The HVPS<br>
consists of microcontroller (&mu;C) based oscillator,<br>
transistor driver circuit, ferrite core High Voltage<br>
(HV) transformer and quadruple voltage multiplier<br>
circuit. The PIC16F84A &#956;C with 20 MHz crystal<br>
generates 9.09 kHz, 96.36%D, 5 V signal which has<br>
been used as a input for transistor 2N2222A driver<br>
coupled with ferrite core HV transformer. Thereafter, the<br>
transformer’s secondary voltage has been multiplied by a<br>
quadrupler circuit. A multi-turn potentiometer would be<br>
used to control the output voltage to a required level.<br>
An assembly language program based on MPLAB<br>
IDE has been developed for generation of the<br>
oscillator signal. The complete High Voltage Power<br>
Supply (HVPS) has been designed and verified in Proteus<br>
7.7 simulation platform.
