SPV Power Conversion using Bidirectional H6 Inverter with reduced Common Mode Voltages

Advantages such as high efficiency, less weight and less cost make the transformer less photovoltaic (PV) inverters most prominent for the modern-day power requirements. The bidirectional capability is absent in the transformer less inverter like, H5, HERIC for the solar power storage system. Investigations are done on bidirectional Inverter/Rectifier to find out the reverse power flow approach. In this manuscript, an advanced bidirectional method is chosen H6 inverter topology is proposed with the altered modulation strategy by keeping the others same. In rectifier and inverter modes of the H6 circuitry, the DM level voltage features is obtained. Meanwhile, with the improved modulation method the leakage current issue is eliminated. Simulations and experiments verify the suggested single phase bidirectional H6 rectifier/inverter technology.
