This project study covers the design and the construction of a Standby Power Supply for Microcomputers. Under normal conditions, the incoming utility power is fed directly into the microcomputer. When utility power fails, the transfer switch of the SPS system senses this condition and turns on the inverter (an alternative AC source), which converts battery power (DC) into an AC source that keeps the microcomputer running. Likewise, when utility power returns, the system transfer switch returns the microcomputer to utility power. It is easy to see why this is a standby technology. The inverter is literally standing by waiting to be turned on.
