Also if we use toff transistor the toff path did not return the gate driver so negative bias voltage meaningles here i suggest to not use it. Now design has two seperate gate resistor for on and off we can arrenged resistor for fast discharge the gateRomale wrote: ↑Fri Jun 17, 2022 10:25 am In this case, the pull-up resistor is made by several kilohms and RG is calculated as before. When a positive pulse is applied, it passes directly through the diode D_ON and charges the Gate of the mosfet. When the output stage of the main driver is closed, then through the pull-up resistor PULL_DOWN opens Q_OFF and instantly discharges the Gate charge through itself, which leads to the instantclosure of the mosfet!

Hi!
in the picture above, there is just one of the best solutions for managing powerful mosfets. I always use this and it works great

Re: all in one board for open inverter project
But I don't know the whole scheme that you use, it can also be good. I would prefer a circuit with a locking transistor, for example Q_off IRFL9110TRPBF, pull_down 4.7K, D_on any schottky per 1 ampere

Hi
The design is done i shared the pdf files if there is no further update i will upload to github

Re: all in one board for open inverter project
The only clarification is that all layers should be made as thick as possible, at least 75 microns, but it is better if 100 microns

I noticed the absence of this place. how to program?

Re: all in one board for open inverter project
also high power path not painted can be supported vıa solder ıt will be reduced the board price
