Programmable AC/DC Power Supply

Abstract

Every electrical and electronic appliance is designed to work perfectly at a certain input voltage. In Pakistan, household electrical and electronic appliances are designed to work properly at 220VAC, 50Hz and most of the time the voltage supplied by distribution companies are as low as 130VAC making this appliance to work under threat of low voltage supply. This low supply voltage causes these appliances to malfunction and in most cases damage them. Since the electric power supply/distribution companies are unable to provide the consistent adequate voltage. We are making this power supply to test different types of appliances to check their durability. This power supply is highly programmable and can perform a wide variety of tests on all kinds of appliances to check their durability and resistance to voltage fluctuation.
