To lower or raise any specific voltage is better adapted from a transformer, but this component does not operate in direct current, which is available in battery or vehicle. Therefore we must put an oscillator that generates an alternative current.

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 […]
