I am trying to get more information about the internals of a backup
generator. Specifically those in the 3kw to 6kw range driven by gas
engines. I have questions like:
(1) What protections do they have against overload? I have been using DC power supplies for 35 years and they all have current foldback that comes into effect when overloaded. Do any generator manufacturers include a similar function?
(2) If the unit has the 240 volt plug, assuming the two hot wires, the
neutral and the ground, how well do they handle load unbalance? For example, if all the load is on one of the legs will that cause any problem.
(3) How do they implement the effect of a center tapped transformer so they "look like" the incoming power line? I have looked over a few in stores and I don't see any transformer.
(4) How do they control the amplitude and frequency of the output?
(5) How close is the output to a sine wave?
Thanks in Advance,
Pete
