I don't think most modern consumer portable generators operate that way, the engine and drivetrain spin at whatever rpm is convenient for the form-factor vs. output power vs. noise level requirements etc. and it's converted to DC then chopped and converted to line frequency AC again as in a car battery inverter-type dealie. |

Most home portable generators are direct drive from the engine. They are less expensive than the inverter type. The inverter type engines run at whatever rpm it takes to produce the power for the inverter part. The speed control for them is a simple goveror set for 3600 rpm. I have two of them rated around 5 kw and one of the $89 Harbor Freight ones that operate that way. |

CVTs are obsolete and not used in homes anyway. That some things don't always survive portable gen power is not news. Portable gens have never had accurate frequency control, or accurate anything control. NT |
