Digital Programmable Power Supply

John Mashurano

Abstract: These days, majority of electronic devices work on DC power source, so there is a requirement of a reliable and customized power supply. Generally, the requirements are not too varied, but still they require every time a new hardware designing. The idea presented here is to build a Digital Programmable power supply that is flexible enough to meet different customer requirements, with minor software changes and no corresponding hardware change. Hardware issues are discussed, with a goal of developing a generalized power supply that has programmable output voltage and current. It is able to recognize faults and take corrective actions to prevent any permanent damage to the system. The system discussed here is capable of functioning independently by its own without any intervention from the user. The system finds application at remote sites to automatically manage primary (AC) and secondary (Battery) power sources to provide smooth uninterrupted power output even during switchovers between AC and DC power sources. It would also be helpful to insurance companies who expect that the products covered by them be reliable, robust and not prone to be damages.
