Does anyone know how to produce a sinusoidal signal to drive MOSFET, such as those in uninterruptible power supplies? Pls. give me some of its specs, links.


thanks a lot.

There are several methods to generate sine waves. Some of them are
Colpitts oscillator
Hartley oscillator
Microcontroller Sin look-up table method
Microcontroller Stepped PWM method

and there's the phase shift oscillator, Wien bridge..



You could even use an 8083, a dedicated waveform generator chip,but an expensive way of doing 8)
