Construction And Evaluation Of A Microchip Designed Ups

Uninterruptible Power Supplies (UPSs) are widely used for power conditioning applications, whereby the load is to be supplied with current and voltage waveforms containing minimal disturbance. A UPS also provides emergency power to critical loads in case of utility mains failure, and as such constitutes an essential element in providing back¬up power for computer networks, communication links, biomedical equipment, and industrial processes, among others. Full hardware-based UPSs are gradually being replaced by microprocessor or microcontroller-based counterparts, with significant improvement in ease of design, flexibility of the control software and overall reduction in development cost. Since a UPS incorporates a relatively large number of detection, protection and control functions,it is important to develop an organised approach to the identification and implementation of these requirements.
