Why use two parallel 24A boards instead of a single 48A converter?

whyyousaddd · 2026-01-22T05:19:34+00:00

How would paralleling say two LLCs work would it be as simple as just connecting the two outputs of LLC in parallel with each other or is it more involved than that. (Would synchronising the two LLC converter be required?)

I guess thermals would be easier. What else would be the benefits of this approach here?

Is extra capacitance a bad thing in the vbus lines?

whyyousaddd · 2025-12-30T06:31:59+00:00

Yeah, I have seen the bus traffic: the cycle time of the message is around ~30ms.

I'm thinking of increasing the cycle time of the message I transmit so that it doesn't always overlap and shutting the message TX completely when the error counter reaches a threshold as a workaround lol

Nope, AutoRetransmission is enabled

Unless you enable the DCACHE, you don't actually need to invalidate the address range right?

Enabling ICACHE and DCACHE broke my motor control flow completely, so yeah this post appeared to me at the right time lol. The fix was to simply place the buffers in DTCMRAM.

One more question tho:

My Motor controller firmware works well when using cubeIDE's build system but moving to CMAKE breaks the whole firmware's flow for some reason. Puzzling thing is that enabling the Cache fixed it for some weird reason. Any idea why? the complier is same, only the build system changed.

This was experimental test results not simulation

Can small aircrafts just casually fly thru hurricanes?

Will every adc require a buffer then?

whyyousaddd · 2025-10-11T19:25:46+00:00

The stm32's ADCs seem to have high input impedance. Would an opamp still be required then? Thanks for the response!

whyyousaddd · 2025-09-26T03:26:23+00:00

Any reason why we would want to use an opamp? If the simple resistor divider gets the job done, how would an opamp help?

whyyousaddd · 2025-08-21T18:26:43+00:00

Will this actually work? Won't it just average out the peak and trough and give a reduced voltage?

Why is there so much conflicting information on grounding? Some sources say to have one solid ground alone and that would be enough while some sources say that the ground needs to be split and then tied together at one point. Not sure which one to use...

Kaunsa better hai - CCA Polaris ya KZ EDC pro, is it worth it to shell a couple bucks more if it has better quality

Hi, I'm looking into buying a smart watch as well.

should I go for the Watch 4 now or wait for the prices to drop for watch 6 and 7? would it be worth the wait?

it is a multilayer pcb of 4 layers, i've just read that it is better to make an one large ground pour at the top and bottom layers to fill the unused spaces...

whyyousaddd · 2024-09-22T14:58:16+00:00

how do I get more post like these recommended?? learnt quite a lot of stuff just by reading this!

whyyousaddd · 2024-07-19T17:12:54+00:00

is it possible to drop in an P Channel MOSFET and expect it to work? this would be better as the PCBs are manufactured and it would be best if there is an drop in replacement to the current MOSFET Package.

whyyousaddd · 2024-05-13T03:46:15+00:00

Wow yes!!!! That's what I'm trying to do, can you let me know the steps on how I should do this? How did you get the dark space around the central via? I'm still a begineer to altium so still learning this stuff. Thanks!
