An FC boost converter (14) is provided with a plurality of conversion units (31a to 31d) each comprising a reactor (32), wherein one conversion unit (31a) is provided with a thermistor (35) for detecting a temperature of the reactor (32), and an ECU (41) restricts the outputs of the conversion units (31a to 31d) at a predetermined change rate. When the temperature detected by the thermistor (35) reaches a restriction start temperature (Tc') obtained from a reference heat resistance temperature (Ta) which is obtained by subtracting an error (ta) of the thermistor (35) from a specification heat resistance temperature (Tmax) of the reactor (32), output restriction of the conversion unit (31a) provided with the thermistor (35) is initiated. When the temperature detected by the thermistor (35) reaches a restriction start temperature (Tc") obtained from an allowance temperature (Tb') which is obtained by subtracting a property variation temperature (tc) of the reactor (32) from the reference heat resistance temperature (Ta) of the reactor (32), output restriction of the conversion units (31b to 31d) which are not provided with thermistors (35) is initiated. |
