![]() Each year, tons of batteries end up in landfill contributing to pollution. 0.5V and 3V capacity of batteries respectively still remain in it which are usually neglected as they become unusable. A 1.5V battery is thrown at 1V and a 9V battery at 6V. Introduction Household batteries that power clocks, torches, remotes, cameras, wristwatches, smoke alarms and portable games and gadgets are so small that they are considered by many to be throwaway items. Keywords: Joule Resurrection, Practical Electronics, Blocking Oscillator,Electromagnetic Induction 1. Since energy is measured in joules and the circuit derives energy out of dead batteries, the name is Joule Resurrection Circuit. This circuit sucks even the last bit of energy from the battery. The second point being, it can operate even when the battery is depleted down to the point where its terminal voltage is around 0.3V. Two interesting things about this circuit are: First, conventional circuit for operating the load is not required. Other advantageous features include optimum power consumption and long life operation. Also, as it is very small, it can be implemented in a large number of applications. This circuit is also known by other names such as Joule Thief Circuit, Blocking Oscillator, Joule Ringer and Vampire Torch. ![]() Normally, it is used to drive small loads. 1 A Review on Joule Resurrection Circuit and its Applications J Sujatha 1, Pradeep Baurai 2, Ritu Sevta 3, SheetalKumari Prasad 4, Anurag Swarnkar 5 and DrSurekha Bhusnur* Scholar, Electrical and Electronics Department, Bhilai Institute of Technology, Durg 6 Professor, Electrical and Electronics Department, Bhilai Institute of Technology, Durg 1 2 3 4 5 6 Abstract Joule Resurrection Circuit may be defined as a boost mode switching supply circuit which is powered by a drained battery.
