Inverter Circuit and Products

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 lastly reaches the secondary coil of a transformer network (2 x 10V/60VA).

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 increase the voltage level to 110V or 220 refer to your needs.

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 will deliver the power output up to 100W and you can use this inverter for battery charger, emergency light and other electronic appliances.

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.
