Speed Up PWM


Recommended Posts

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.
