Is there something better than a PTC thermistor for limiting the line-current inrush to a conventional bridge->cap SMPS front-end?
(I'm charging 15uF from the 120VAC line, so the inrush will stress parts and pit switch contacts if you energize the switch just when the line voltage hits peak.)
I never liked the PTC scheme--it seems you could fool it by cycling power after it's already warmed up.
I designed an active limiter, but it seems there should be a better way. Just wondering what you guys do...
