40W Inverter Circuit 12VDC to 110/220VAC

40W Inverter Circuit Diagram

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.

Inverter, is an electronic device or circuitry that changes direct current (DC) to alternating current (AC). The input voltage, output voltage and frequency, and overall power handling depend on the design of the specific device or circuitry. The inverter does not produce any power; the power is provided by the DC source.

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.
