Claim 20:
21. An electronic power system which provides single or multiple phase AC power having parameters including but not limited to voltage, current and frequency, the AC frequency being changeably controllable to assist in managing the loading of the power system, the power system comprising at least:
a) a power source comprising one or more DC to AC inverter circuit which receives DC power from a DC power source and converts it to AC power having a changeably controlled frequency;
b) a power source monitor circuit which may be part of the power source or otherwise operating in response to the operating condition of the power source to control the AC power frequency to be one of a plurality of frequencies including at least a first frequency which represents when the power source is being operated with loading that does not create an overload and a second frequency which represents when the power source is being operated with loading that if continued will risk damage to or loss of power by the power source;
c) the power system further comprising a coupling circuit for controllably coupling at least some of the AC power from the power source to at least a first load of one or more loads, the coupling being responsive to the frequency of the output AC power in a manner such that it performs at one or more of helping to prevent overloading; helping to mitigate overloading or helping to not increase the overloading of the power source.
