A Novel Single Phase Eleven-Level Grid-Connected Transformerless Converter Topology for PV Systems
M Vinay Kumar [2] | B. Naresh [4]
Abstract: The multi-level inverters are used in high power and medium voltage applications, since 1975 and are gaining much attention due to numerous advantages like common mode voltage, operation at both fundamental and high switching frequency, drawing input current with low distortion, reduced harmonic distortions. This paper proposes a single-phase eleven level transformerless grid-connected photovoltaic converter. The common-mode leakage current is minimised using a transient circuit and efficiency is improved by regulating flying capacitor voltage with suitable switching strategy. Simulation results show the effectiveness of the proposed topology.
