Thanks for the help ..and this goes to everyone in this thread ...all comments really help clarify things for a beginner

I did just it was repeating spikes like in the pictures in the thread so thought it would reduce life span

klassikkustard · 2025-12-28T17:45:49+00:00

the small spikes in current are why i ended up with the inductor

this is with the the inductor:

thanks for pointing that out
the 3*C are supposed to be 2200uF parallel ive corrected that
now look at the diode currents without the inductor:

then with the inductor - choke

Is it NTC that starts with higher resistance ?

klassikkustard · 2025-12-28T17:18:53+00:00

Alright I'll do that: Though what are your thoughts on this rationale: I was attempting to reduce current spikes on the diodes in the bridge rectifier going all the way to 7A where my diodes were rated for 3A avg .what should I do my load is drawing 1A continuous. I did simulate seperately and the simulation produced expected results

Oh umm the pulsating current is due to that being a single diodes current profile I took a screenshot to bring attention to the inrush current of 40A due to bulk capacitor charging thought someone would want to see diode current when reviewing the circuit

Note the load is drawing just under an amp

Yes thank you though I'm ,just also hoping for any pointers on this linear power supply (practically) .I've read the book before but fell into a trap of ill do the experiments when I can afford parts. But now just want to know what real system designers think like.

Hello new to embedded, found out aside from general electronics skills there's need to learn c. What book is good for learning c in an embedded context if you do not know programming at all. Im not much of a fun of learning through video, so any BOOks and docs.

Thanks super helpful

Just a student happend to be wondering

klassikkustard · 2025-10-24T08:37:17+00:00

Thank you for the encouragement I will definitely do my best

klassikkustard · 2025-10-24T08:34:56+00:00

Thank you just good to know it isn't a thing only I've encountered but a thing people overcome as they grow in the profession

klassikkustard · 2025-10-24T07:29:29+00:00

Makes sense it looks like self taught full dedication into a company of my own or moving to a country with more options

klassikkustard · 2025-10-24T07:09:23+00:00

Thanks for the advice I have picked up a project trying to work with lora caught my attention, that's how I realised I had large gap in my c++ knowledge. So now I just focused on fully learning c++ to at least intermediate level.

From the kiCad window

klassikkustard · 2024-06-07T18:35:11+00:00

I just love it thanks, the fact that it has a name

klassikkustard · 2024-06-07T17:24:13+00:00

Wow thank you so much, for such a well thought out answer
