Digital Variable power supply

The advent of industry, hospitals, retail outlets and computers and computer controlled equipment entering the rural domain of India has necessitated the requirement of variable power supply for variety of equipment. For meeting this requirement a multipurpose supply source is envisaged. Until now, the digital supply has carried a variety of meanings: one whose parameters or functions are set digitally by external logic signals; or a power supply for a "digital system," like a cell phone; or a power supply providing a digital readout. The greater functionality and new monitoring features of today’s power supply requires more sophisticated control and communications. In addition, requirements for lower costs, smaller form factors and compressed development cycles continue to escalate, pressing power supply designers as never before. The digital power supplies are proving to be a better and futuristic option over the analog power. The architecture of the microcontroller is out of the preview of this paper. A variable power supply is one where you can continuously adjust the output voltage to your requirements. The conventional controlling method of variable power supply that uses manual interference (using a rheostat) has been replaced by a servo motor which is controlled by a micro-controller. This in turn reduces the pain of adjusting the rheostat manually and also increases the efficiency of the system. Varying the output of the power supply is the re-commended way to test a project after having double checked parts placement against circuit drawings and the parts placement guide. Aimed at solving the practical problems envisaged in the power supply to the rural areas of India .It is a practical application of software for the controlled power supply from a single platform to a varied variety of equipment expected to be used in hospitals, BPOs etc. The software programming has been incorporate d using C language and has been kept out of the purview of this presentation as the program itself is a subject of independent presentation. The design has been made incorporating user friendly features and easy usage for the operation. CONTACT ON : 9503784350 , 020-65001020.
