| May 29, 2019 at 12:54 | comment | added | Sieben | I put from 4khz to 20khz. Know that 817 optocoupler is best till 8khz. Know about the linear mode are not good. But why then with 2n2222 all the same? Only right gate drivers will solve? Also if such state with transistor, that should be all the same with transistor exit optos like 4n35? | |

To the greatest extent possible, your system should only ever be fully on or off. Moderation is via the time average of the PWM. | |
