CONVERTER CONTROL DEVICE

摘要

A converter control device includes a converter device (30) formed by three converter circuits connected in parallel between a secondary cell (10) as a first power source and a fuel cell (12) as a second power source. A control unit (40) includes: a PID control module (42) for controlling the converter device (30) by PID control and executing a desired voltage conversion; a drive phase quantity modifying module (44) for modifying the number of drive phases of the converter device (30) in accordance with the passing power of the converter device (30); and a gain switching module (46) which switches the PID control feedback gain when modifying the number of drive phases.
