Abstract	Instant Power Supply unit (IPS) is an electrical device that provides power when the main supply fails to operate. In the present work an attempt has been made to design and develop an instant power supply unit at the electronics laboratory of department of Physics, Jahangirnagar University. In the present circuit active and passive devices, such as diodes, transistors, capacitors, resistors etc have been used. Two transformers (One Step up and one step down) have also been used in this work. A voltage regulator (LM 338K) is used in the charger circuit so that the battery will be charged properly and will not be over charged. As a result the battery will get long life. Also the output of the device will be automatically stable. A relay circuit has been incorporated so that when the main supply is present the battery will automatically be charged and not provide any output. The main supply would come to the output of the IPS through the relay circuit. The designed circuit is operated successfully and the results obtained are satisfactory.
