This is the circuit diagram of inverter for 8W fluorescent lamp. The circuit is build based ZTX652 transistor, and used to drive an 8W fluorescent lamp from a 12V source. The inverter will work from 10V to 16.5V DC supply, attaining efficiencies up to 78% thus making it suitable for use in on-charge systems such […]

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 […]

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 […]

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 […]

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.

This simple inverter circuit 12VDC – 220VAC contains a central part, the CMOS 4047, and converts a 12V DC voltage to 220V AC voltage. The 4047 is applied as being a astable multivibrator. At pin 10 and 11 we obtain a rectangular symmetrically signal that is amplified by two Darlington transistors T1 and T2 and […]

This is the schematic diagram of 300W power inverter circuit. The circuit use timer IC NE555 as to produce the wave / AC voltage signal. The signal the fed to the final amplifier to be amplified and to powered up the signal. There are many 2SD1047 transistor to amplify the signal. The transformer used to […]

This is the 100W DC inverter build based transistored multivibrator as well as transistor signal amplifier. The inverter will convert 12V DC voltage in the input and increase the voltage level to become about 220V AC. 12V car battery is recomended to be used as the input, transistor 2N3055 is used as the amplifier. It […]

This 250W inverter circuit converts the 12V DC input from car battery. The output will be 120V AC or 220V AC depended on the transformer used. The inverter work at 60Hz frequency.
