Efficient power supply is necessary in all the machines to make them work properly with minimal losses. Power supply is used to supply power to electro-chemical machine which is use for machining of metal plate (work piece) with maximum accuracy. Therefore this is application based power supply. This work mainly concentrates on reducing the power losses and get variable value of output voltage and current. Simple control strategy is using to reduce loss and improve the quality of power supply. Control schemes with less complexity and computation has been proposed and developed for enhancing power supply quality and to get variable output quantity value. In this technique rectified voltage is obtained in accordance with the output voltage i.e. output voltage is given to the input side as a feedback and according to the output voltage, input voltage will be adjusted. The proposed power supply is simulated and implemented in hardware. Simulation is done for different reference values and different output values. The hardware is implemented for specific application which has certain range of output voltage and current. Human machine interface is used in hardware to control the system, to get drilling details such as how much deep drilling is required. In this arrangement, auto controlling is done to protect the system if any fault comes or any quantity exceeds its limit. © Research India Publications.
