Supercharged joule thief circuit
WebAug 4, 2011 · The Joule Thief spends most of its' time storing energy in the transformer, and then dumps it in a short blast through the LED. You measure such a low voltage because the voltage is only present for a very short period of time. It happens so rapidly (130kHz) that it looks to you like it's on continuously. Bernard Joined Aug 7, 2008 5,784 A joule thief is a minimalist self-oscillating voltage booster that is small, low-cost, and easy to build, typically used for driving small loads. This circuit is also known by other names such as blocking oscillator, joule ringer, or vampire torch. It can use nearly all of the energy in a single-cell electric battery, even far below the voltage where other circuits consider the battery fully discharged (or "dead"…
