Claim 8:
9. The power converting apparatus of claim 8, wherein the inverter controller comprises:
a first current command generation unit configured to generate (i) a current command value based on calculated or sensed rotor speed information of the first motor and (ii) a speed command value,
a first voltage command generation unit configured to generate, based on the generated current command value and a detected current, a voltage command value for driving the first inverter,
a first switching control signal output unit configured to output, based on the generated voltage command value, a first switching control signal for driving the first inverter, and
a maximum torque calculation unit configured to (i) calculate a maximum torque per ampere (MTPA) based on an output of the first current command generation unit and (ii) output, to the first voltage command generation unit and the converter controller, the current command value corresponding to the calculated MTPA.
