Abstract

A power source system () includes a direct current power source (), a direct current power source (), and a power converter () having a plurality of switching elements (S-S) and reactors (L, L). The power converter () performs a direct current voltage conversion between the direct current power sources () and a power source line (PL) in parallel by controlling the switching elements (S-S). Each of the switching elements (S-S) is disposed to be included in both a power conversion path formed between the direct current power source () and the power source line (PL), and a power conversion path formed between the direct current power source () 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 (), and a carrier signal used for a pulse width modulation control to perform the direct current voltage conversion for the direct current power source () is controlled according to the operation condition of the power converter ().
