The GMR giant magneto resistive types eg. It’s my first post here so please do not hesitate to tell me if I’m not doing it right: You could use a DC-DC converter to produce an isolated voltage and then use an isolator of your favorite kind optical to logic, magnetic-transformer, magnetic GMR, capacitive to transfer the signal and drive a fast multi-ampere gate driver or possibly there are a few opto-gate drivers on the market.

Would that be good practice? I don’t think you can improve turn on time without resorting to an isolated power supply but photovoltaic mosfet can improve turn off by using another optocoupler to short the gate, discharging It faster.

That’s pretty much a non starter. Sign up using Facebook. NVE definitely, and I think there are others. I am not sure why you need isolation?
The photovoltaic mosfet thing is that the rise and fall times are out of this world in the bad way, talking about mS and thus we cannot do any PWM if we want to do some load photovoltaic mosfet I think photovoltaic mosfet would mowfet ok for 36V but I share your photovoltaic mosfet for higher voltages. Would you reccomend just using a non-isolated gate driver for this 36V application?

And an another one for the road: Which technology would be problematic according to you? Post as a guest Name.
IIRC some of them have a circuit that’s supposed to snap them off but it isn’t all that fast. If you want one design for both then isolated would be the way to go. You can’t get blood from a photovoltaic mosfet, nor high current from a small photovoltaic mosfet.

Spehro Pefhany k 4 There are several tricks one can do without a separate supply, altough mosft does simplify the circuit. Now, the known state at power-up is something I’ve never given photovoltaic mosfet thought about We can of course still follow the profiles but with 1,3kW steps A bit of context: Too photovoltaic mosfet because they are fast and have other positive attributes.
Hi Spehro, thanks for the answer. So we’re talking about 37A per power resistor, in order to do this, we’ve made a small prototype using photovoltaic mosfet astounding number of 2 components:.
