Impedance Design of 21-kW Quasi-Z-Source H-Bridge Module for MW-Scale Medium-Voltage Cascaded Multilevel Photovoltaic Inverter Conference Paper

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 (2) 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 2 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 2-ripple model and impedance design method. 2014 IEEE.
