Description.

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.

Notes. 

Use a 12 V battery as the DC voltage source. Use a 8W florescent lamp as load. 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.
