In order to increase voltage from 12 to 18 volts using the same power source, you need a step-up converter. The circuit is easy to design, as it employs only one integrated circuit (IC), which has an oscillator and an op amp. The output is. As gasoline becomes more expensive, the environment more threatened and technological breakthroughs more common, electric cars are finally on the verge of becoming a viable alternative. Because production models, such as the Tesla Roadster. Simple AC Electric Generator With an AC DC Converter: In this project we are going to show you how to make a simple AC electric generator. With this generator we can light up a small LED light. We also made an AC DC converter to show that o.
