Design and Development of a PIC Microcontroller Based High Voltage Power Supply

Design, development and simulation of a microcontroller based high voltage power supply HVPS have been presented in this paper. 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, 5V 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. M. N. Islam | M. S. Alam | S. Sultana | H. Akhter | M. A. S.
