Abstract: 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).

Abstract: An operation mode selection unit selects an efficiency priority mode for minimizing the overall loss in a power supply system based on a load request voltage obtained in accordance with the condition of a load and on the conditions of DC power supplies, and generates a mode selection signal in accordance with the selection result. When SOC and/or output power have/has reached power supply restriction values in any DC power supply, an operation mode modification unit generates a final mode selection instructing signal so as to modify selection of the efficiency priority mode by the mode selection signal to select an operation mode in which power distribution between the DC power supplies can be controlled.
