NettetThe joule thief (aka blocking oscillator) is an electronic circuit that allows you to make use of batteries normally considered dead. A battery is often considered "dead" when it can't power a particular device. But what's … 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 … Se mer Prior art The joule thief is not a new concept. Basically, it adds an LED to the output of a self-oscillating voltage booster, which was patented many decades ago. • US Se mer • Armstrong oscillator • Blocking oscillator • Flyback converter • Forward converter • Switched-mode power supply Se mer The circuit works by rapidly switching the transistor. Initially, current begins to flow through the resistor, secondary winding, and base-emitter junction (see diagram) which causes the transistor to begin conducting collector current through the primary winding. … Se mer Simulations and implementations • Joule Thief Simulation • Simulation and efficiency comparison of different Joule Thief versions - archived 2024-10-30 Se mer
