Практический реверс‑инжиниринг источника питания Murata
Один из лучших способов изучить силовую электронику — это реверс‑инжиниринг качественных изделий. Недавно я полностью воссоздал DC/DC‑преобразователь Murata мощностью 369 Вт — от многослойной печатной платы до принципиальной схемы и конструкции магнитных компонентов. В этой статье хочу поделиться с вами своим практическим опытом реверс‑инжиниринга импульсного источника питания RBQ-8.2/45-L48NBL2-CIS2.

You can use a buck converter as a buck-boost converter. As in, get negative voltage.
I just checked. On paper. And guess what? They are nearly identical. The schematic of one turns into the other.
The only difference is the negative side of the input capacitor.
Mind=blown.There are application notes for how to reconnect your converter, but even they don't notice it's THE SAME TOPOLOGY! https://www.ti.com/lit/pdf/slyt286

Protect 24V DC branches instead of risking full panel shutdown.
Send your control panel load details to SMIDMART for product support.

Selecting an SMPS for a control panel? Do not choose only by output rating.
Share your panel load list with SmidMart for faster SMPS sourcing support.

PLC panel random reset? Do not blame the PLC logic first.
Check the 24V DC power system: SMPS capacity, voltage drop, grounding, distribution, and branch protection.
Weak power design can cause unstable inputs, relay chatter, and machine stoppage.
Share panel load details with SmidMart for SMPS and protection selection support.

More #electronics questions.
The MCP1623 boost converter.
They recommend a 4.7µH inductor, and they support boosting from 3.4V to 5V. At low currents, the efficiency can drop to 0.6.
TI Application Note SLVA372D gives inductor ripple current as T*Vin*D/L. That works out to
> 3.4V * 0.6 / (270kHz * 4.7µH)
680/423, approx. 1.607565 ampere (current)which is WAY above the converter's switching current.
And yet, it works.
What is wrong with my calculations?

Continuing on the "Hangell" switching bench power supply I received a few weeks ago...
I mentioned there was some switching noise visible on the output - not a lot, but more than I'd ideally want. Today I built a filter for its outputs, with a large-ish common-mode inductor/choke rated 10 mH (accurate enough, though my meter says it drops to about half that at 100 kHz) sandwiched between a couple of 1 μF class X2 safety capacitors.
It seems to have done the trick. Under a moderate load, all the random hash has disappeared, leaving only some spikes at the switching frequency, and those are much smaller than they were before. The RMS noise value is now (barely) under 1 mV, if you believe my cheapish oscilloscope.
Like a lot of switching supplies, there's a lot of open space in the chassis, so I had room to squeeze the filter inside. I'm pretty happy with it!
Now to see if this no-brand thing works for any length of time.

How to calculate the voltage undershoot (ΔVo) of an SMPS during a load step (ΔIo)?
ΔVo = ΔIo/ (2π fc Co)
where
fc = Cross-over frequency of the control loop
Co = Output capacitance -

Проектирование импульсных источников питания: ключевые параметры и распространенные ошибки
В этой статье мы рассмотрим проектирование импульсных источников питания: ключевые параметры и распространенные ошибки. Импульсные источники питания (SMPS) стали стандартом в современной электронике благодаря высокому КПД, компактности и гибкости применения. Однако их проектирование связано с рядом сложностей: от правильного выбора топологии и компонентов до грамотной разводки печатной платы и обеспечения электромагнитной совместимости.

I just found my bi-polar SMPS power supply that I bought for an audio project. A friend also designed a filter board to remove the high-frequency noise generated because it is a switching supply.

Can somebody please explain to me, why so many switch mode power supplies (#smps) don't implement adequate inrush current limiting? So many just put the primary side capacitors right after the rectifier…
I just had a UPS release the magic smoke from its output IGBTs, just because of the (standby) inrush currents into the bunch of PSUs it was serving.

I played around with switch-mode power supply circuits in Qucs-S tonight.
It's interesting how mutli-phase buck converters make almost all problems smaller; smaller/cheaper inductors, smaller output capacitance, smaller transistors required. The only down-side I can see is that the transistors have to be faster or you have higher switching loss.
