Hardware Implementation of Z-Source Inverter Based MPPT Scheme for Solar Power Conversion System

Abstract:

In this paper, the implementation of Z-Source Inverter based on Maximum power point tracking scheme (MPPT) for photovoltaic (PV) System is employed. This proposed work has the advantage of more power yield with reduced switching elements in power conditioner. Also a single stage power conversion circuit possessing Z-source network which replaces the boost converter set up in conventional mundane maximum power tracking circuits. The maximum power tracking is the trickiest part which is embedded within the inverter control. Therefore the control over inverter not only operates the PV panel at its maximum possible power but also have a check at the capacitor voltage of the Z-source network, thereby making the system more reliable and power efficient.
