Abstract (en)
[origin: EP2680668A1] In the case where two or more inverter circuits 9 of a plurality of inverter circuits 9 are driven at the same time, control means 25 drives the inverter circuits 9 at the same driving frequency, acquires output currents of the driven inverter circuits 9, and performs drive control for the inverter circuits 9 in such a manner that the phase difference between the acquired output currents is reduced. Furthermore, the load determining means 26 performs a load determination on the basis of output currents of the driven inverter circuits 9 detected by output current detecting means 28 and input power or output power detected by power detecting means.
