For once again I'm in need of your expertize. I'm building an H-Bridge and I want all components to be N channel, for that reason I need to use optocouples for at least high side mosfets.
So far I used a CYN17 - 3 with some success at 10kHz.
I really don't know if I need to go beyond the hearing range for optimum PWM, still I need a faster optocoupler.
It's not that the CYN17 isn't working but it's introducing me a phase delay, cause of it's rising and falling time, which is just not good...
Before telling me that a N-channel H-bridge is an over kill and so on, please guys I got everything else covered, and everything else seems to work fine, at least on multisim...
So I just need a easy commercially, fast switching (rising/falling times negligible at 20kHz) optocoupler. Have anything to suggest?
Thanks in advance, please let me know, cause I'm really in a hurry.
Best Regards, Lefteris
