摘要：
Due to high switching frequency and modulation strategy, neutral point clamped (NPC) inverter generates varying common mode voltage as well as leakage current in PV and wind turbine system. This leakage current causes electrical hazard, THD at the output voltage, EMI and ultimate pollution at the output power. To reduce this varying common mode voltage and leakage current, this paper proposes a Split Inductor based Neutral Point Clamped (SINPC) inverter with improved modulation technique. The proposed inverter can reduce common mode voltage and suppress leakage current comprehensively. In order to verify the effectiveness of the SINPC inverter with improved modulation, simulation has been carried out in PSIM software. Finally, the output wave shape of reduced common mode voltage and leakage current ensures the effectivity of the proposed circuit.
