This is the 40W inverter circuit diagram. The inverter converts 12V DC voltage from battery to 110V AC output with 40W power and it will be 20W for 220V AC output. It can be use for electronic device such lamp, LCDTV, laptop etc with maximum power of 20W (220V) and 40W (110V). The inverter circuit is based CD4047 works as multivibrator to generete a waveform signal. Transistors BC 337 & TIP 3055 is used as complementary symmetry amplifier to gain the power, amplify the waveform voltage level.
The tranformer used to step up the waveform signal (AC current) for powering the 110/220V electronic devices. Please be careful since this circuit produce high voltage output.
