    摘要: If it is determined that excess power is generated based on overcharge information of a power storage device, a controller starts an operation of consuming the excess power by an excessive power consuming circuit. The controller counts elapsed time from the time point when the power consuming operation started, and if the counted elapsed time exceeds a minimum on-time set in advance, switches the excessive power consuming circuit from active to inactive state. The minimum on-time is set based on a pattern that is expected to cause generation of excessive regenerative power from an AC electric motor because of abrupt change in running status of an electric powered vehicle mounting a motor drive system.

    摘要: In the hybrid vehicle, a boost converter is controlled to make a post-boost voltage or a voltage on the side of an inverter become a target post-boost voltage corresponding to a target operation point of a motor in accordance with a target post-boost voltage setting map that divides an operation region of the motor into a non-boost region and a boost region when a operation point of the motor is included in the boost region. The target post-boost voltage setting map is prepared so that the non-boost region includes a region in which a loss produced by driving the motor when not boosting the post-boost voltages becomes smaller than the loss produced when boosting the post-boost voltage and the boost region includes a region in which the loss produced when boosting the post-boost voltage becomes smaller than the loss produced when not boosting the post-boost voltage.

    摘要: It is determined that a periodic zero current stagnation state is reached to correct a voltage command of a smoothing capacitor downward by a predetermined voltage when a state where a current (reactor current) flowing through a coil in a dead time when switching elements are both off immediately after the switching element (upper arm) is turned off from on stagnates at a value of 0 occurs at switching periods of the switching elements. This can prevent a voltage of the smoothing capacitor from becoming unexpectedly higher than the voltage command in the current stagnation state, prevent the smoothing capacitor from being damaged by an overvoltage and prevent excessive torque from being output from motors.
