<P>PROBLEM TO BE SOLVED: To provide a parallel operation controller of an inverter generator which allows parallel operation of a plurality of inverter generators outputting a three-phase AC. <P>SOLUTION: In an inverter generator 10A comprising first, second and third inverters 22a, 22b, 22c each connected with three windings wound around an engine-driven power generation part and outputting an AC power by performing DC/AC conversion of an AC output power by using the switching elements, and first, second and third control units (CPU22a2, 22b2, 22c2) which control on/off of these switching elements, and can be operated in parallel with at least one inverter generator 10B of the same configuration with three-phase AC output, interphase voltages and interphase currents input from the generator 10B are detected when the U-phase terminal, V-phase terminal, W-phase terminal of the output terminals are connected with the U-phase terminal, V-phase terminal, W-phase terminal of the generator 10B, and on/off of the switching elements are controlled so as to synchronize the interphase voltages and the interphase currents with detection values. <P>COPYRIGHT: (C)2013,JPO&INPIT |
