4W/12V Fluorescent Lamp Driver

Fluorescent Lamp Driver

Basically, this 4W/12V fluorescent lamp driver circuit is a small inverter circuit with very small power output that is about 3-5W. This circuit can be used to power up a 4W fluorescent lamp from 12V battery. It uses a normal 120 to 6V stepdown transformer in reverse,  to step 12V to about 350V to drive a lamp without the need to warm the filaments. The 555 timer IC is wired as an astable multivibrator. The output signal which generated by multivibrator from the IC are amplified by the power MOSFET IRF510.

Inverter Circuit for Florescent Lamps

Inverter for florescent lamps

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

Simple Inverter for Soldering Iron

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.

Simple Inverter 100W with FET IRF540

Simple Inverter Circuit 100W with FET IRF540

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.
