A novel switched-capacitor based single-phase five-level transformerless inverter

This paper proposes a 5-level single-phase transformerless inverter topology for grid-connected PV applications. The new topology makes use of a switched-capacitor network on the input side and eliminates leakage current completely by maintaining the Total Common Mode Voltage (TCMV) constant. The proposed inverter topology has the advantage of complete multi-level performance resulting in low harmonic distortion in the output voltage and...
