Abstract
A constant-frequency electric power source including an A.C. generator having a field coil, to be driven by an engine and a converter unit which includes a rectifying circuit and an inverter. A controller controls the A.C. generator, and the A.C. generator has at least two groups of multi-phase output coils, one group of the at least two groups of multi-phase output coils being connected to the converter unit for providing an A.C. electric power with a constant-voltage and a constant frequency to be supplied to a first load, and the remaining groups of the at least two pairs of multi-phase output coils being connected to other loads respectively. The output of the remaining groups is supplied to the A.C. generator controller thereby controlling the input of the field coil of the A.C. generator. The A.C. electric power used for the first load is different from the A.C. electric power used for the other loads.
