Abstract

The invention provides a method and apparatus for controlling a converter in a fuel cell vehicle. The apparatus comprises a first amplifier, which is configured to take the power control value controlled by the converter power as the reference value and generates a current reference signal based on the reference value; a current sensor, which is configured to detect the current of the output terminal of the converter; a current controller, which is configured to compare the current reference signal with the detected current of the output terminal so as to finally output the final reference signal; a triangular wave generator, which is configured to generate triangular waves; a second amplifier, which is configured to amplify the generated triangular waves; and a comparing unit, which is configured to compared the amplified triangular wave signals with the final reference signal so as to output the pulse wave signal for controlling the converter.

Description

technical field [0001] The present invention relates to the control of inverters, and more particularly to apparatus and methods for controlling high capacity inverters used in fuel cell vehicles. Background technique [0002] Fuel cells convert chemical energy generated by oxidation of fuel into electrical energy. Although both fuel cells and batteries utilize chemical cells that carry out redox reactions, in batteries the cell reactions are generated in a closed system whereas in fuel cells fuel and oxidant (reactants) are supplied continuously from outside the system and then When the reaction occurs, it will be continuously removed out of the system again. In recent years, fuel cells have been commercialized, and since the reaction product of fuel cells is pure water, research related to water as an energy source for environmentally friendly vehicles has been actively conducted. [0003] In order to efficiently use energy, fuel cell vehicles utilize a hybrid system wit...
