<p>PROBLEM TO BE SOLVED: To provide an inverter controller including a small capacity capacitor capable of optimizing the efficiency of a motor drive system by controlling a regenerative energy from a motor utilizing the motor with an increased reluctance torque ratio.SOLUTION: The inverter controller including a small capacity capacitor 32 has drive control means 6 including a current phase difference adjustment section 14 that adjusts a phase difference of the current with respect to an induced voltage generated by the motor 5. The current phase difference adjustment means performs phase adjustment so that the voltage output from orthogonal transforming means 4 is a predetermined set value or less, and at least one of the values of an average value of a torque command value or a current command value given to the motor 5, an average value of effective values of armature currents detected by current detection means 7 and an average peak values of the armature current is a minimum value.</p> |
