<P>PROBLEM TO BE SOLVED: To test an inverter while simulating a motor operation without connecting the motor which is an actual load to the inverter. <P>SOLUTION: The tested inverter 1 and the inverter 2 for a dummy load are connected through a transformer 8. To a motor simulation operation control part 11, a speed N of an IPM motor, armature resistance R, inductance Ld, Lq, L on shafts d, q of a stator, and induced voltage constant ϕa are input, output currents iu, iw controlled by a current control method and output voltages vu', vw' from a filter 7 are input and an impedance between the inverter 1, 2 is changed from resistance to inductance in accordance with each output voltage. That is, the amplitude and phase of output voltage of the inverter 2 are controlled with respect to the output voltage of the inverter 1 to change the load from the inverter 1. By controlling the amplitude and phase of the output voltage of the inverter 2, operation of the motor is simulated. <P>COPYRIGHT: (C)2008,JPO&INPIT |
