Power Sine Wave Circuit
I am trying to build an economical circuit to power an AC electromagnet.
The energy source has to be a battery, preferably less than 24v. The power draw of the electromagnet will be about 500W (the application requires a high-power alternating magnetic flux).
I'm thinking of making a sine-wave generator and a simple transistor amplifier with high power transistors.
Can anyone suggest circuits for this? My knowledge of electronics is not that great, but I'm quite enthusiastic about this and I believe I can give it a try. Any help will be appreciated.
