In fuel cell systems, voltage balancing is an important consideration. The utilization of a modular construction based on a three-level boost converter was able to balance DC voltage. This paper investigates the effect of parameter variations, such as inductors and capacitors, on the converter's steady-state controllable areas. The plot of the inductor current and the voltages of the output capacitors are illustrated for different scenarios. The system simulation results were performed using MATLAB / Simulink software.


  • DC modular converter is considered to balance the output voltage.
  • DC modular converter can be used in fuel cell applications.
  • MATLAB/Simulink software is used to plot the waveforms of the system.
  • Changing the values of capacitors and inductors did not affect the capacitance-voltage balance in the steady-state regime.
  • The inductance and capacitor values do not affect the controlled zones.
