Here the very simple inverter circuit for florescent lamps. This inverter is absolutely very easy to construct, well-performing, and also strong enough to power up a 15W florescent tube (when you cool the transistor properly). The only hard-to-find component of this circuit may be the so-called yellow inverter transformer. It is a miniature high frequency transformer which has a 25mm x 20mm x 5mm ferrite core, 30 turns of primary, 15 turns of feedback, and 250 turns of secondary all concentric, wound on plastic frame than wrapped using a ‘yellow’ adhesive tape. In case you cannot get it at electronic store around your location then you may try to find old portable rechargeble florescent lanterns because they’ve at least a single yellow inverter. Of course it is possible to wind a handmade transformer which would do the same but it is really hard to do if you don’t have an original to inspire and it will still require an proper ferrite core.
Simple Inverter for Soldering Iron. Right here is a very simple but low-cost inverter for making use of a small power soldering iron (25W, 35W, and so on) in the absence of mains supply. It requires eight transistors along with a number of resistors and capacitors.
Transistors T1 and T2 (each BC547) build an astable multivibrator that generates 50Hz frequency of wave signal. The complementary outputs from the collectors of transistors T1 and T2 are fed to pnp Darlington driver stages formed by transistor pairs T3-T5 and T4-T6 (using BC558 and BD140). The outputs from the drivers are fed to transistors T7 and T8 (each 2N3055) linked for push-pull operation. Use appropriate heat-sinks for transistors T5 through T8.
This is the simple inverter 100W which use CD4047 CMOS IC as signal generator and MOSFET transistor IRF540 as signal amplifier. Field Effect Transistor (FET) is better than ordinary transistor in both stability and responsibility. You’ll need a 2-3A center tapped transformer to deliver 100W power output.
Here the simple 100W inverter circuit which will convert the DC voltage of 12V from car battery to become an AC voltage of 220V. This inverter apply famous CMOS IC of CD4047 squarewave oscillator to generate 50Hz squarewave frequency and use power transistors of 2N3055 to amplify the signal from CD4047.
