WebFeb 8, 2024 · Joule thief dc/dc converter driving an LED. A rapidly switching NPN transistor is the basis of a Joule thief dc/dc converter. This circuit will typically switch at 5 to 40 kHz with about a 30% to 50% duty cycle when driving a small 3.0V LED from a 1.5V “AA” battery. WebMany of us are interested in the Joule Thief, the common name for a voltage boosting converter which allows a 1.5-volt or lower battery source to operate an LED which requires upwards of 3-volt to light.This circuit uses a single-transistor blocking-oscillator which features a coil with a secondary winding to generate timing signals to maintain oscillations.
WebHow can I calculate a Joule thief. A Joule thief is a simple step-up converter with which you can drive a 3.6 V LED with a 1.5 V battery even if it is spending the last drops of its life. It merely consists of a transistor, a transformer and a resistor. The circuit is very forgiving especially concerning the number of coils of the transformer. Webjoule_thief.pdf Download Ask Question Step 1: Construction Details I use prototype strip board for this. 4x7 is all you need for this circuit but of course you can be more generous …
WebThe joule thief 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"); hence the name, which suggests the notion that the circuit is stealing energy or "joules" from the source - the term is a pun on the age-old expression "jewel thief".
