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