Abstract

This paper proposes a 1 MW grid-tie photovoltaic system by connecting quasi-Z-Source (qZS) networks into Cascaded H-Bridge (CHB) inverter. The proposed Power Conditioning System (PCS) consists of a 3-phase 48-cell CHB inverter where each module is fed by a qZS network. The proposed topology allows boosting the input voltage to a higher level while solving the traditional imbalance problem of DC-link voltage in CHB inverters. A multilevel output voltage waveform is produced using an enhanced phase shifted pulse width modulation technique, which inserts shoot-through states into the conventional zero states to control the qZS-CHB module. The effective control schemes are proposed to achieve grid-tie current injection, low Total Harmonic Distortion (THD) current, unity power factor, and DC-link voltage balance for all qZS-CHB inverter modules. A 1 MW system is built in MATLAB/SIMULINK environment to verify the proposed multilevel PV energy conversion system and its control principles.
