Hi guys!
I am trying to design a bowl feeder for an application
I need to give basically 2 features:-
Vary voltage And vary frequency
Input is 230v AC 50 Hz
for varying voltage I'm thinking of using a chopper
But for varying Frequency I could use a little help
Maybe somewhat like PWM using IGBTs
I need to vary frequency from 50Hz to 100Hz
Please suggest

 

So frequency from 50Hz to 100Hz. At what range of voltages and at what current?

 

It is not difficult to generate a low frequency (sine?) Wave.
