<P>PROBLEM TO BE SOLVED: To provide an inverter testing device, capable of performing simulation for a vehicle-mounted inverter of which the respective conditions for simulating the motor such as a rotational speed of the motor change, corresponding to the changes in motor generation torque due to the changes in the actual vehicle speed. <P>SOLUTION: A phase-number conversion portion 16 outputs two phase current id, iq from output current iu', iw' of the tested inverter. A gate signal is generated by output voltage Vu, Vw and two phase voltage Vd*, Vq* from a motor torque computing portion 18, to control a motor simulating inverter. A motor simulator 17 outputs motor inductance Ld, Lq. The motor computing portion 18 receives the inductance and outputs torque τ. A vehicle simulator 19 changes the motor rotational angle speed ωm, based on torque τ corresponding to the motor rotation, disturbance torque Mr and the amount of inertia Jc of a motor shaft conversion which a vehicle load amount computing portion 20 computes, thus outputting to the motor simulator 17 and the phase-number conversion portion 16. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
