It takes a steady low voltage signal and. A Joule Thief is a self-oscillating voltage booster. Sometimes you have to kick an oscillator out of an initial, metastable state so that it starts reliably at a user defined time in the simulation. This circuit used in this project is a modified Joule Thief. Simulate > Time Domain > Run Time-Domain. XFRMR1 forms a centre tapped inductor However, CL takes a long time to run the simulation. V1 (vcc) has exponential ramped startup to kick-start oscillation. Now, it does not show the exponential rise of V1 and does not start oscillating unless. Pretend for a moment, the battery in the moment isnt connected. Turns out, you still cant get something for nothing. Without load (the LED) I have measured voltages over 30 V. Joule Thief circuits got a bad rap some time ago because some people in the over-unity, free-energy crowd went nuts over it, so lots of people wont really spend any time talking about it. The explanation of what a joule is can be found on the Wikipedia page here. Normally the Joule thief produces output voltage, which value is difficult to predict. CL have changed something in the simulator because this used to run with the sim set up as. Basically, what the Joule Thief does is it 'steals' every last Joule of energy from your batteries.
