Preventing spikes in inductor current (probably) caused by lab power supply
As part of a university project I'm trying to produce a current through an inductor (610uH), that'll eventually be used as a solenoid. I'm producing this using a PWM voltage produced by a TI GaN ...

Inductor magnetic field collapses during switching?
SEE EDITS BELOW
I'm running into some problems with my Buck converter design. During the switching period the inductors magnetic field seems to collapse, which generates some large voltage peaks. That'...

Why is an inductor rather than a capacitor used to smooth switch mode regulators
I understand (at least at a high level) how to use both capacitors and inductors to reduce noise but I don't understand the advantages/disadvantages of each approach or why one is chosen over the ...

How does the inductor current ripple influence a switch-mode power supply?
I am looking into several DC/DC switching controllers. When talking about component selection, many datasheets and application notes say that inductor ripple should be kept around 20-40% of the ...

Step Down Switching Regulator irregularity with ripple on output
Using the L5973D- I have followed the Schematic as the datasheet instructs, but I have tried two different inductors. I have found problems with other systems on the board with the one inductor (744 ...

Which current ripple equation should I use? (Boost converter)
I am designing a boost converter for a microgrid as an university project. It is supposed to interface a 2.4kW 120V solar array (using MPPT) with a 380V DC bus. There will be other sources and loads ...

5V DC over data lines
I am prototyping the below diagram and using the following Common Mode Choke from Murata 50475C (4.7mH DCR 0.7R). When I input a signal on U1 Point B 3Mhz D = 50%, I can see AC coupled signal on U2 ...

Spikes in Inductor Current : Buck Converter
What could be the reason of such spikes in inductor current at each Switch ON-OFF. ??
This spikes are also getting affected in load current.
Please help me to reduce / remove this spikes.
