İs this only challenging part for is there any other out of stock components if you didn't order we can make updates

Also i can add 7805 regulator so you can use both sr2803 circuit will be DNP if you are using 7805 vice versa

Yes we can change it give me suggestion

Also there is DNP resistors i will write it today

I also could not find the ratings of these resistors: R56,R57,R133,R134,R135,R136,R137,R153,R154,R155,R156,R157,R167,R168,R169,R170,R171,R178,R179,R180,R181,R182,R189,R190,R191,R192,R193,R200,R201,R202,R203,R204 Those are pull down resistor in locking circuit it can be several k ohms like you said ...

I understand that. but we still need developer comments on many points. for example, is -3 volts used from all other dc/dc, or can I buy single-channel ones with an output of +15 volts? for all these resistors, there are no specified values and it is impossible to send an order to the manufacturer ...

Something is wrong in the scheme. The output of the DC-DC has a voltage of 18.3, and the chip that it feeds is powered by 5V. Maximum 5.5. IMG-20220809-WA0007.jpg Yes romale you are right but in bom it already written as 5 v output DC DC converter with same pages i copied from gate drivers converte...

İ will check c130-c153

İ can sent sr2803 chip

Or replace it with yours if you not produce the boards

The BOM file is done.

hello. could you give an explanation on this "thing"
IMG-20220716-WA0002.jpg

Hello

This is room for every sheet you can delete it or it can stay

Hi

The BOM file is done.

Please refer to BOM file for exact component name and package.

I also uploded file to github

Also i would like to thank you for such project

it is done https://github.com/haliltepedelen/all-in-one-board-for-open-inverter-project-V2 Hi! I downloaded the files. I will send it in the near future for the manufacture of boards. Most likely, they will install all the small parts there, but DC/ DC and power mosfets will already be bought separ...

Hi

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

Hello. I think everything is fine. I can try to make

Now ı wıll make fınal check for production

Ok i will make layer stack table for manufacturing

also high power path not painted can be supported vıa solder ıt will be reduced the board price

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

Hello

I placed 4 pin header close to the microcontroller also can be programmed via esp8266

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...

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_DO...

do you think locking drivers will be needed for heavy-gate transistors? When I did without them, the mosfet did not close for a long time and there was heating. I started using a locking driver and everything started working fine. Hi We can try this solution but we are also using neagative gate vol...

The Kelly KLS7230C controller uses 30 mosfets to-220 to 100 amperes and it perfectly outputs up to 300 amperes of battery current and up to 450 amperes of motor current. It seems to me that if we implement 30 mosfets of IRFP4568PBF, we will easily get 600 amperes of motor current and up to 500 ampe...

Hi I am working on it also i redesigned the board but the current sensor you shared is not suitable for pcb mount need check another one if it is ok for you I think that the current sensor can be put aside on the phase terminals. By the way, how are you supposed to implement the phase output? How i...

Hi I will make the changes; mosfet and hall sensors Hi! How are you doing in changing the board? I can't wait to make and test for bugs and on a motorcycle. And then summer will fly by quickly and it will be cold))) [/quote Hi I am working on it also i redesigned the board but the current sensor yo...

Thanks

I am working on it now i will upload files when its ready

Yes ı really would like to test it

Hi, so if you can fix the board to use 30 mosfets to-247 and replace the hall-based current sensors (I'll give a link to a good sensor) I will produce at least five samples at the same time, tob can be used on different equipment by conducting comparative tests! https://aliexpress.ru/item/100500317...

Romale wrote: ↑Sat May 21, 2022 10:37 pm Hi! I would like to try to make it, but with an amendment to 136 volts (32s li-ion) and the most powerful mosfets possible

Hello Romale

Thanks for your interest yes we can try with 136 volt

You can share the process here so forum and me can help

thanks
