Abstract

An impedance parameter design of quasi-Z-source (qZS) H-bridge inverter module applied to megawatt (MW)-scale medium-voltage Photovoltaic (PV) power system is proposed. A double-line-frequency (2ω) voltage and current ripple model of qZS network with PV panel is established. The effects of qZS inductance and capacitance as well as PV panel terminal capacitance on 2ω voltage and current ripples are investigated by using the built model. Elaborate designed prototype parameters are to buffer those low-frequency ripples. Simulations are carried out on a 21-kW single-phase qZS PV inverter to verify the proposed 2ω-ripple model and impedance design method.
