As one of the crucial components in residential BESSs, two-stage single-phase inverters realize bidirectional energy flow between low-voltage residential energy storage batteries (40–60 V) and the AC grid.
Residential battery energy storage systems (BESSs) have garnered attention as an effective method to improve the economic efficiency of rooftop photovoltaic (PV) generation, due to their abilities to increase self-consumed of PV energy and decrease residential electricity bills , , , .
Within two-stage inverters, front-end DC/DC converters process DC voltage matching, while downstream DC/AC inverters convert DC voltage to AC voltage to meet load consumption or grid-tied demand.
Various single-phase inverter topologies have been studied , , with the H6 bridge topology notable for its advanced hybrid modulation strategy that mitigates leakage current, common-mode voltage issues, and supports bidirectional power flow .
