In electro-tech-online I asked about my need of making a device wich could generate a sinusoidal signal (by PWM method) with a 18F4550 Ucontroller, but it seem it is not possible. Someone named Dana suggested me to see the information about this cypress device.  So, the questions are:

1. Is it possible to make a threephasic 5 KHz signal (3 120 degrees unphased signals), wich could be used by a power stage to handle about 1 ampere each branch in some kind of power transistors?

2. If the signal is analog, is it a way to isolate the control stage from the power stage?

3. Is it possible to stop or restart this signals with a Ucontroller signal?    Or further, to control amplitude?

4. Do this device is sold and there are existences now on Mouser, Arrow or DigiKey?

Thank you for your time

Luis
