Inverter Circuit for Florescent Lamps

inverter for florescent lamps 300x228 Inverter Circuit 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.

This really is a single transistor oscillator circuit. The electric current passed via primary winding inducts a magnetic field to the core and the core provides the power back to the feedback winding having a delay determined by the core material and windings. System then oscillates continuously on a frequency determined by this timing. It’s not possible to use 2SD882 with voltages more than 4.5 volts. It is only necessary in case you are going to supply the circuit with only 4.5 volts. Equivalent transistors may possibly not work as great as 2SD882.

A power inverter is a device that converts DC (Direct Current) power into AC (Alternating Current) power. The AC output is usually 120 VAC, 60 Hz (USA domestic power) or 230 VAC, 50 Hz (International power). Inverters are usually used to supply AC power from DC sources such as solar panels or batteries
