This circuit is used to drive a regular a/c cfl bulb upto 32 watts. You can try it by using more watts bulb or changing the transformer. The output of the sg3525 is fed to the transformer through two Mosfets. The pinout diagram of sg3525 is given below:
C1- 0.001 uF (102)
C3- 4.7 uF/25V
C4- 0.001 uF (102) 1Kv
L1- Choke(100 uH)
T1 – CFL Transformer (EE28)
MOSFET (Q1 & Q2) – IRF540/ IRFZ44/ P55NF06
Diode(BR) – D1-D4 – BA159
Fuse (F1) – 1A
Battery – 12V or Two 6V Battery in series or Three 4V battery in series.More battery ampere used, more duration.
The circuit do not include charging section. Tested up to 32 Watts cfl bulb without any heat sink. Can also charge mobile or tabs. Requires 12v battery of any ampere. We can also use computer ups battery.
