This circuit is self-oscillation push pull chopper circuit. It is supplied from 24V battery. Its frequency is 4kHz. Its major advantages are: 1. It does not require choke, and it only uses 0.12μF small-capacity capacitor to limit lighting tube current to belower than 630mA; 2. chopper transformer is much smaller than low frequency period; 3. when it isin high frequency, the efficiency is high. Main technical data of the circuit:working volt: 24V working band: 4kHzcurrent sinking: 4.5Aconsumed power: 108Wlamp power: 65Wefficiency: 60% Transformer data:n1=n2=10turns, 1.0mm copper lacquered wiren3=n4=2 turns, 0.75mm copper lacquered wiren5=120turns, 0.75mm copper lacquered wire
