First and second converters (10 and 12) are connected in parallel to positive and negative lines (PL3 and NL), respectively. When a required power (PR) is smaller than a reference value, an ECU (30) controls the first and second converters (10 and 12) such that one of the first and second converters (10 and 12) operates and the other stops. When the required power (PR) is equal to or larger than the reference value, the ECU (30) controls the first and second converters (10 and 12) such that both the first and second converters (10 and 12) operate. |
