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.
