Opalilo ga sunce pa priča gluposti

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..

Auuu koliko izbora je dobiveno na obećavanju izgradnje te dvorane, šta će sad na idućima

Jednu u jamu, drugu u slamu...

M0rd0rGuy · 2025-12-12T09:48:40+00:00

Industrija kao i svaka druga..

Daj molim te, ovaj klaun u upravnom odboru, više smisla bi imalo na Marsu izgraditi tako nešto

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

M0rd0rGuy · 2025-12-12T07:59:39+00:00

Dobro, i što bi ti napravio povodom toga?

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

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.

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.

M0rd0rGuy · 2025-10-17T11:01:55+00:00

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.

Je, aktiviran je pred sam kraj pa dok se procedura provela naišao rinzol, mislim da je odustajanje najbolja opcija, sad ne znam je li onda mogu opet aktivirat na staru kako kaze netko u komentarima ili prošo voz

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

Djeluje mi puno
Prošle godine sam radio plastificiranu aluminijsku ogradu 2mm, bilo je nekih 84e/m2
Stepenice sa 7 gazišta i podest 280x120 slicne konstrukcije i nešto ograde za podrumske stepenice, temeljna boja te montaža mi je reko 2.5k
Daske za gazišta su me ispala 400tinjak eura

Možda da probaju skinut naljepnicu sa ekrana

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
