abstract
This research paper article work focussed on the development of an extra high gain boost DC-DC converter for high voltage dc application with simple closed loop control scheme is presented. Classical version of stepup voltage DC-DC conversion configurations are used in high power (voltage/current) applications, but they are limited due to the restricted voltage transfer gain ratio, less efficiency, and moreover require two sensors with complex control algorithm lead to non-economical utilization. Further, the effect of parasitic elements limits both output voltage and power transfer efficiency of dcdc converters. But with the application of voltage lift techniques pay the way to overcome these limitation, opening reliable way to improve the performance characteristics. Complete model of the proposed high gain DC-DC converter along with simplified closed controller was implemented in numerical simulation software using Matlab/Simulink environment and hardware prototype was realized using DSPTMS320F2812 with resistive loads. The performances are investigated under both line and load perturbation conditions. Numerical simulation results along experimental verifications are provided with complete theoretical developments.
