Construction And Evaluation Of A Microchip Designed Ups
MetadataShow full item record
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.
