This inverter circuit is extremely simple to construct, trustworthy, and even effective adequate to light up a 15W florescent tube (if you cool your transistor nicely). The only hard-to-find piece of this circuit will be the so-called yellow inverter transformer. It really is a miniature high frequency transformer that features a 25mm x 20mm x 5mm ferrite core, 30 turns of main, 15 turns of feedback, and 250 turns of secondary all concentric, wound on plastic frame than wrapped having a 'yellow' adhesive tape.
If you cannot find it within your regional electronic shops then search for old portable rechargeble florescent lanterns considering that they have at least a single yellow inverter. Naturally you can wind a handmade transformer which would do the same nonetheless it is actually a really tough job if you don't have an original to inspire and it'll nonetheless require an proper ferrite core.

About Inverter
An inverter is an power electronic device that converts direct current (DC) to alternating current (AC); the converted AC can be at any required voltage and frequency with the use of appropriate transformers, switching, and control circuits. Solid-state inverters have no moving parts and are used in a wide range of applications, from small switching power supplies in computers, to large electric utility high-voltage direct current applications that transport bulk power. Inverters are usually used to supply AC power from DC sources such as solar panels or batteries. It will be useful for emergency electric source
