A study on a standby Power Supply unit incorporating an inverter circuit has been made. This supply unit is capable of supplying 24O V output continuously. The inverter used here employs two darlington transistor which are enabled once the main supply is cut-off. The inverter used source is achieved by rectifying the a.c. mains. In the event o-f mains -failure, the inverter will take its power supply from the battery. A change over from mains to inverter supply is accomplished by mean of a three—pole relay unit. In this study a model of the Stanby Power Supply units was made and tested. The construction and testing of this unit was succesfully done in the laboratory.
