Speed Up PWM

[Mike]

I'm using the V350-TU24 for PWM control of a powerful chopper. Since the controller uses RC-circuit, is not possible to get the output high frequency and sharp edges. I had to climb inside) and found the magic point.

The result is a control on the chopper frequency of 8 kHz (via optocoupler..). But there is a downside - only 32 steps adjustment duty cycle.

And by the way, HS input is also modified to measure frequencies up to 100 kHz.

You have definitely picked the right avatar. There's nothing like a successful hack to get the job done.

I can't wait to hear what the Home Office in Israel has to say about this one.

The Home Office says you hack at your own risk...any such hacking voids all guarantees, warranties, and we recommend against it....
