 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

Inverter builders might be interested in these, sounds expensive for experiments though (snap! crackle! pop!) |

Technology advances.... not sure how many makers will be requiring > 1000v devices for an inverter; look on Microchip's web site and they have none in stock until near the years end. I'm trying to source some >200 amp mosfets with 3.3v gate drive at the moment, everyone is out of stock, cannot get anything until 2022 - 2023, welcome to the global chip shortage. Cheers Mike |

Ok Mike, I'll bite what are the 200A 3.3V gate drive mosfets for? I can only imagine that they are essentially a slow on off switch driven directly from the micro? Tell me more I am intrigued, it certainly doesnt sound like a normal inveter topology. If at first you dont succeed, I suggest you avoid sky diving.... Cheers Mike |

Sorry zeitfest, didn't mean to hijack your thread... Yep mostly correct, 3.3v Pico board driving some alarms, one of which is a large truck air horn, draws 50 amps on start @12v, the surface mount mosfet will turn the horn on\off in bursts to prevent its motor over heating; mosfets Ron approx 0.001R. Makes it easier to implement than a large expensive relay, may have to modify the design, not going to wait over a year for parts.  |
