Z-source active power filter with a fuel cells source

This paper proposes a Z-source active power filter with a fuel cells source instead of conventional V-source active power filter. Z-source impedance network along with shoot through capability of the proposed system would ensure a constant DC voltage across the DC link. As the compensation and control algorithm of the Z-source active power filter, a single-phase instantaneous reactive power theory is adopted. The effectiveness of the proposed the system is verified by the PSIM simulation in the steady state and the transient state.
