Not so much with smaller battery chargers but anything that draws significant current (like an RV or Boat inverter/charger system) usually trips it. I've had problems with three different RV's. Works fine on a non-GFI circuit. I know of nothing in a switcher that should trip a GFCI and I have a couple of PCs that run just fine on the GFCIs. Current may lag voltage but Dr Kirchoff says the current in will equal the current out at any given instant and that is what a GFCI compares. AFCIs are different, they actually look at current "signatures" and those spiky switching power supplies can trick one. I bet your charger has regrounded the neutral, probably through an RF filter. That is usually the culprit. Wayne has the answer, A transformer. If the noise is not an issue to you, disconnecting the filter is always an option or just couple it to ground through a capacitor.. Low current devices like a PC usually are not a problem although nuisance tripping has been reported. Higher current draw devices (like an RV inverter/charger have more issues. There's nothing wrong with the inverter/charger or the GFI. It's a reflected component of the high frequency power supply induced into the power source line that confuses the GFI. Not an issue unique to my experience. You can find discussions on it elsewhere. Wayne's transformer recommendation works just fine. I ended up having to use a Hughes Autoformer for the RV's in Florida because the voltage where we were often drooped significantly during parts of the day. I measured as low as 105 vac at times. As an experiment, I tried using the Autoformer back up in MA on the GFI circuit and everything worked fine. You are not getting much isolation with an autotransformer. The primary and secondary are tied together. It still might solve the problem thought because the connection is on one if the circuit conductors so the differential toroid in the GFCI sees the current as being balanced I still say if you are tripping a GFCI, it is because there is a circuit from the line conductors and ground, usually a RF suppressor. It will be designed to pass more if you have a higher current switcher. I know there is plenty of "discussion" and plenty of theories but the guys who actually design them have the opinion I trust. Isolation transformers are effective in quenching noise (and in some cases arcs) that can be induced either in the supply side or by the item being powered. Basically acts as a big choke. Ever notice what's missing in high frequency switching power supplies? Big, heavy, iron core transformers. Switchers are great but they can be noisy. |

Perhaps you and Flatulent Jim should have nightlights installed inside your skulls so you're not totally in the dark. -- Just because you are opposed to abortion doesn’t make you pro-life. Your morality is deeply lacking if all you want is a child born but not a child fed, not a child educated, not a child housed, not a child clothed, not a child able to see the doctor. That’s not pro-life…that’s pro-birth. |

Earlier this year I saw a report that concluded that troubled sleep from even minimal light sources could have major effects on the health of people. They even recommended dark colored pillow slips and sheets, let alone eliminating night lights, lighted clock displays etc. This might explain some of your problems...such as needing Valium before a somewhat simple dental procedures. |

I don't pretend to be a great white hunter engaged in the non-sport of shooting animals with a gun. Refilled one and two liter plastic bottles at 50 and 100 yards are colorful targets. Just bought a steel "gong" to take out to the range and hang on chains. I don't remember anyone here saying they hunted to prove any bravery. It has been presented as a way to put food on the table. The rest of that is just in your head. There's a slight chance we might be able to extend the range out from 100 to 200 yards, depending on interest and how many guys want to chip in for the grading and planting. If it happens, it'll be done in the spring. You are destroying more habitat. Way to go. What does he care as long as he and his boyfriends have a place to frolic and shoot guns. |
