Hi!
With traditional linear powers supplies, an incadescent light bulb works nicely in series with the mains in order to debug PSU issues without blowing a lot of fuses/components.
But how do I do something similar with switch-mode power supplies? I've read several comments other places stating that this is not safe in the SMPS case. Is this true? And if so, what can I do to achieve a "soft start" for my SMPS so that I can detect problems without blowing fuses and/or components, other than disconnect it from the circuit that it is powering?
Specifically, I'm trying to fix the SMPS in a Tektronix 2213A. I have another thread on that, but I wanted to ask in general about SMPS (if such a generalization is possible, of course).
Best regards,
