Matrix Frequency Converter - read description

AC -> AC direct frequency converter without a rectified DC intermediate circuit. Input is on the left side, output is in the middle.

I was only able to fit 1 phase in, but if you had 3 of these, you could run a 3 phase AC motor making a variable frequency (to control the motor’s RPM) from a fixed frequency 3 phase power supply.

The entire appeal of a matrix frequency converter is the wide range of output frequencies, but the EveryCircuit canvas is pretty small, so it wasn’t really possible to fit a more complicated driving circuit for a variable output frequency.

In this case it’s a fixed 2:1 ratio … 50Hz input and 25Hz output, but feel free to play around with the pulse generators.

Please correct me if the name is wrong. I’m not 100% sure this is a matrix frequency converter, because I am studying electroengineering in a different language. I hope the description isn’t a mess . . .
