Abstract: An apparatus for controlling a converter in a fuel cell vehicle uses a current control value generated based on a voltage of a DC terminal of an inverter as a reference value and generates a current reference signal according to a change rate based on the reference value. The final reference signal for generating a PWM signal is outputted by compensating the current reference signal based on a current of an output terminal of the converter. Also, the converter is controlled by generating the PWM signal with a duty ratio by increasing a peak by amplifying a triangular wave signal and comparing the amplified triangular wave signal with the final reference signal which is compensated according to the change rate of the current reference signal.
