If it is determined that excess power is generated based on overcharge information of a power storage device, a controller (30) starts an operation of consuming the excess power by an excessive power consuming circuit (20). The controller (30) 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 (20) 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 (100). |
