Claim 33:
34. An electronic power system which provides AC power to one or more loads, the power system comprising at least:
a) an AC power source having one or more DC to AC inverter which converts DC power to AC power which may be controlled to change to different known frequencies, the AC power source having at least one timely operating parameter from which an overload of the AC power source may be determined;
b) a power source monitor operating in response to the at least one timely AC power source operating parameter to control the AC power frequency to have a timely one of a plurality of frequencies including least a first frequency when there is no overload and a second frequency when there is an overload;
c) the power system further comprising a first coupling circuit for controllably coupling the AC power to at least a first load of the one or more loads in a manner to mitigate overloading of the power source after the AC power takes on the second frequency; and
d) further comprising a second coupling circuit for controllably coupling the AC power to at least a second load of the one or more loads, the second coupling circuit being responsive to at least one AC power source timely operating parameter, which may be the same as or different than the at least one timely operating parameter of b) to perform at least one of i) prevent an overload, ii) alleviate an overload or iii) prevent further overload if the power source is already overloaded.
