Abstract: Control mode switching determination is made as a part of a main loop (control period for overall control of an AC electric motor. When switching from the rectangular wave voltage control mode to PWM control mode is determined, the change in voltage phase of the rectangular wave voltage is inhibited from the timing of control mode switching determination until the next execution of the main loop until the timing at which the control mode is actually switched, to maintain voltage phase of the rectangular wave voltage at the time of control mode switching determination. Consequently, in a drive controller for an AC electric motor allowing switching between control modes, control mode can appropriately be switched without destabilizing the operation of the AC electric motor.

Abstract: A triangular-wave current flows through a reactor of a DC/DC converter for converting voltages between increased and reduced levels. Surges are reduced, which are developed in an output voltage serving as a control voltage when the triangular-wave current changes across a zero value at which the current direction is changed. When a primary current flowing through the reactor changes across 0 [A] (zero value) at which the direction is changed, within an adjustment range, a feedback coefficient by which to multiply the error between the control voltage and a target voltage is multiplied by k (k>1) so as to increase a feedback amount. Surges developed in the control voltage due to a dead time when the primary current changes across 0 [A] are reduced.

Abstract: An ECU activates a shutdown permission signal and provides it to an AND gate when a shutdown signal is inactive. Thus, when an abnormality sensing device does not sense an abnormality, the ECU always keeps the shutdown permission signal active. The AND gate performs logical AND between a signal provided from the abnormality sensing device and the shutdown permission signal to provide the shutdown signal to inverters. When a limp-home run permission signal becomes active while the shutdown signal is active, the ECU inactivates the shutdown permission signal.
