Features of connecting a fuel cell stack to the three-phase load
In this study, a comparison of methods for connecting a fuel cell stack to a three-phase load was researched. The stack connection via a current source inverter and a voltage source inverter was considered. The study was conducted using simulation modelling in the MatLab/Simulink software. Simulation models of the operation of a fuel cell stack on a three-phase active-inductive load through a current source inverter and a voltage source inverter were created. The harmonic composition of the stack voltage, stack current, and load phase-to-ground voltage curves was studied. Losses in semiconductor converters and inductances were estimated. The influence of the switching frequency of semiconductors on losses in the current source inverter and voltage source inverter was studied.
