Hello,
i have posted few threads earlier regarding my project.
Its an AC ~ AC converter. I need a variable frequency 3phase voltage.
Iam expecting 10 - 100Hz range.
For this i took HEF4752.
I found only two articles based on this IC and the datasheet is also not satisfactory.
Any ways. i have designed the circuit.
I observed the six pulse trains in three dual trace oscilloscope at a time.
Im veryu much satisfied with this. see the schematic attached.
But the problem comes here. Whenever i connected the pulses to the 6 mosfet bridge, all the mosfets are blowing up......
First i used STW7NA100 mosfets..... later i tried with IRFZ44....
What should i do......
I have one doubt. What is the imortance of a mosfet driver?
Is it that much imortant? I have used six 4N35 optocouplers. Is it ok?
Help me plaese
