Abstract: A system and method for controlling an induction motor which basically achieve reductions in a steady state loss and in a transient loss of the induction motor such as a stepwise input of a torque instruction value T.sub.e *. Basically, a steady-state loss minimization magnetic flux calculating section calculates a secondary (rotor) magnetic flux .phi..sub.r * which minimizes the steady-state loss of the induction motor in response to a torque instruction value. A target magnetic flux .phi..sub.r and a differentiation of the target magnetic flux d.phi..sub.r /dt are thereafter calculated using a low pass filter transfer function such as .phi..sub.r =.phi..sub.r * 1/(1+.tau..sub..phi..S)(, wherein .tau..sub..phi. denotes a time constant, and S denotes a Laplace operator). A target torque T.sub.m is calculates using a predetermined transfer function in response to the torque instruction value such as T.sub.m =T.sub.e *.1/(1+.tau..sub.T.S)(, wherein .tau..sub.T is a time constant for the target torque). At the steady state, the slip frequency .omega..sub.se is set to a loss minimization slip frequency .omega..sub.se-opt and, at the transient state, a magnetic flux response gives an optimum value corresponding to a torque response described above. The induction motor is used to drive an electric motor-driven vehicle.

Abstract: An electric power converter, electric power conversion system and method that, without using a DC-DC converter, uses and allots the electric power of plural power sources while reducing the volume and losses. At least one phase of the motor is connected to plural power sources and generates and synthesizes pulses from output voltages of plural power sources so as to drive the multi-phase AC motor. A different phase of the motor is connected to one DC power source and generates pulses from the output voltage of the power source so as to generate a driving voltage for the multi-phase AC motor. This arrangement allows use/allotment of the power of plural power sources with a reduced number of semiconductor components.

Abstract: Limits are imposed on a fundamental voltage command value calculated at a fundamental current control circuit that controls a fundamental component of a 3-phase AC motor current in a dq-axis coordinate system rotating in synchronization with the rotation of the 3-phase AC motor by using predetermined limit values and limits are imposed on a higher harmonic voltage command value calculated in an orthogonal coordinate system (a higher harmonic coordinate system) rotating at a frequency set to an integral multiple of the frequency of the fundamental component in the 3-phase AC motor current by using a predetermined limit values. The voltage command values resulting from the limit processing are added together and a voltage corresponding to the sum is applied to the AC motor for drive control.
