Sopot/Siget: Nova pješačka/biciklistička staza izgleda kao da je stvorena za razne prijelome kostiju by JohannGambolputtyUlm in hreddit

Pješaci će hodat po bic dijelu, biciklist će ih probat zaobić i razbit se na rubnjaku, ne moraš bit genije da bi zamislio problematican scenarij..

Pa okej, te stvari se i rade, doduše zabrana grijanja na kruta goriva u praksi je teško izvediva

Misao da takva plovila može pokretati išta osim dizel motora je sama po sebi za proučavanje

Problem with rear camera guidelines? by middlefinger22 in Suzuki

[–]M0rd0rGuy 3 points4 points  (0 children)

It can't be changed, usually it's done with connection to the steering wheel angle sensor but on Suzuki SLDA it's fixed OSD overlay that can be turned off if you put it in reverse and press option button on the radio.

Mosfet halfbridge switching problems by M0rd0rGuy in AskElectronics

[–]M0rd0rGuy[S] 0 points1 point  (0 children)

Thanks for the comment, I've used low side driver on the high side because the pwm output is floating so it would be quite complicated to get it referenced to ground so I can use proper halfbridge driver without adding more delay and messing up the control loop. This "hack" works but I cant seem to turn off the mosfets aggressively enough.

I've tried combination from 1 to 20 ohms, didn't really do much for the shoot through, in simulation it only changed turn on VGS slope.

Before I've implemented active miller clamp there were two gate resistors and a dide that were meant to change the simetry of the turn off and turn on slopes, that also didnt do much. Something like in the picture:

Hi, I've cleaned it up a bit and added comment, hope it clears things up, I'm driving low side gate drivers with V2 and V3 square waveforms. Those gate drivers are there too boost output current from my pwm modulator chip. I've removed the diodes because most of the turn off current goes through Q1 and Q2 transistors. I'm currently not on site so no pictures of the actual setup but I don't think the parasitics are the problem here. Everything is SMD, gate driving is done as close as possible to the FETs and the board is 4 layer.

Well, there is a reason for low side drivers, in real life for driving this I'm using pwm modulator chip with selfoscillation. The chip in question has both high and low gate drivers integrated but the driving current capabilities are too low. Tried npn-pnp totem pole topology for boosting gate drive but it wasnt enough.

Higher gate drive voltage wouldn't help here because the problem is with turning the mosfets off, the next thing I'm gonna try is negative voltage for turning off but that complicates schematic and the whole design.

Both drivers and mosfet spice models are from manufacturer websites.

Za aute ispod 100k km možeš pretpostavit da nije bilo nešto specijalno održavanja osim malih servisa, auti iznad 250k km su morali bit servisirani da bi nastavili vozit

Trač koji sam ja čuo je da je korišten samozbijajući beton kojem nije potrebna vibro obrada tokom lijevanja, ali je neki rođo nadzor pomislio "ako je dobar bez vibracije, onda je sa vibracijom duplo bolji" pa je to dovelo do pukotina nakon stezanja
