A Parallel Operation System of the Z-Source Active Power Filter with Fuel Cells System

This paper proposes a parallel operation system of the Z-source active power filter using one fuel cells(FC) system. The proposed system is composed of two Z-source inverters operating in parallel only one PEM(Polymer Electrolyte Membrane)FC system. Also, as the control algorithm of the active power filter, a single phase P-Q theory and PI control are adopted. The effectiveness of the proposed the system is verified by the PSIM simulation in the steady state and the transient state.
