8W Flouroscent lamp driver

Posted on Feb 6, 2014

Here is the schematic of a simple flouroscent lamp driver circuit based on two transistors. The circuit uses capacitive ballasting for driving the tube. An 8 W standard flouroscent tube can be efficiently driven using the circuit. The two transistors (2Sc 1983) with associated components forms a oscillator around 1KHz. The oscillator is wired so that

saturation condition of the transistors are prohibited. This adds on to the efficiency of the circuit. The circuit produces a clean sine wave with very less noise. The winding details(no of turns) are given in the circuit. Use 0. 8 mm dia enameled copper wire for primary and 0. 4 mm dia enameled copper wire for secondary. The core can be a ferrite core. The primary should be wound first and secondary on top of it.
