    摘要： A power source system (5) includes a direct current power source (10), a direct current power source (20), and a power converter (50) having a plurality of switching elements (S1-S4) and reactors (L1, L2). The power converter (50) performs a direct current voltage conversion between the direct current power sources (10, 20) and a power source line (PL) in parallel by controlling the switching elements (S1-S4). Each of the switching elements (S1-S4) is disposed to be included in both a power conversion path formed between the direct current power source (10) and the power source line (PL), and a power conversion path formed between the direct current power source (20) and the power source line (PL). A phase difference (φ) between a carrier signal used for a pulse width modulation control to perform the direct current voltage conversion for the direct current power source (10), and a carrier signal used for a pulse width modulation control to perform the direct current voltage conversion for the direct current power source (20) is controlled according to the operation condition of the power converter (50).

    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.
