Claim 10:
11. The power converting apparatus of claim 10, wherein the inverter controller comprises:
first and second current command generation units each configured to generate (i) a current command value based on calculated or sensed rotor speed information of the first and second motors and (ii) a speed command value,
first and second voltage command generation units each configured to generate, based on the generated current command value and a detected current, a voltage command value for driving the first and second inverters,
first and second switching control signal output units configured to output, based on the voltage command value, first and second switching control signals for driving the first and second inverters, and
first and second maximum torque calculation units each configured to (i) calculate a maximum torque per ampere (MTPA) based on an output of each of the first and second current command generation units and (ii) output, to the first and second voltage command generation units and the converter controller, the current command value corresponding to the calculated maximum torque per ampere.
