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.
Posted a new video, was working on an alternate way to recharge the house batteries during an extended power outage.
Learning about switched mode power supplies.
How do I limit #current on the output side?
All regulators I could find connect the SENSE pin on the input side.
But my #bike #dynamo input will have variable voltage, so it's useless.

A project about projects. FesZ Electronics is a channel about various electronic projects I spend my free time doing. It will go from educational stuff like tutorials, to teardown reviews to just putting ideas into practice. The point is to do something with educational value, not just fun.
