A simple idea presented herecan be built at homeusing most ordinary components to produce reasonable outputs. It may be used to power not only the usual electrical appliances but also sophisticated gadgets like computers. Its inverter circuit utilizes a modified sine wave design. An uninterruptible ...
The frequency is determined by R1, R2 and C1. The output of IC-1 is connected to resistor R4 and the trigger input lead of IC-2. IC-2 is also a 555 timer IC and configured as an inverter. The output pin 3, of IC-2, is always the opposite polarity of the output pin 3 of IC...
