How to Design an Uninterruptible Power Supply (UPS) Circuit
In this brief tutorial I have explained how to design a customized UPS circuit at home using ordinary components such as a few NAND ICs and a some relays. What is an UPS UPS which stands for uninterruptible power supply are inverters designed to provide a seamless AC mains power to a connected load without […]
