Quote from: midali on Sep 21, 2021, 12:00 PMWhen connecting in parallel, the capacitance of the FET Gate will increase, which will be 7x. Even if it is a decent frequency of 1 khz, you will have to use the fet-driver to control them. Why do you want to use 7 in parallel?
Quote from: John Lawton on Sep 22, 2021, 09:38 AMWhy would you need 1kHz PWM to control resistive heating loads? Use a fraction of that frequency or indeed don't use PWM at all, some form of pulse density modulation should be fine.
