The　instantaneous　output　power　of　the　two-stage　inverter　pulsates　at　twice　the　output　frequency,　resulting　in　the　second　harmonic　current　(SHC)　in　the　front-end　dc-dc　converter.　To　reduce　the　SHC　in　the　inductance　branch　while　maintaining　good　dynamic　performance,　this　paper　proposes　a　control　scheme　based　on　a　new　inductor　current　feedback　path　in　the　front-end　buck　converter.　In　the　scheme,　through　the　equivalent　gain,　the　virtual　resistor,　and　the　bandpass　filter,　the　inductor　current　is　fed　to　the　front　of　the　voltage　regulator.　The　feedback　function　simplification　is　studied　and　the　implementation　of　the　proposed　scheme　is　illustrated.　With　considerations　of　both　reducing　the　SHC　and　improving　the　dynamic　performance,　the　parameter　design　approach　for　the　feedback　function　is　also　presented　for　the　proposed　SHC　reduction　control　scheme,　and　the　performance　analysis　and　comparison　from　the　viewpoint　of　output　impedance　are　provided.　The　simulation　model　and　the　prototype　of　a　10　kW　two-stage　inverter　are　constructed.　The　simulation　and　experimental　results　about　the　low　SHC　in　the　front-end　buck　converter　and　the　fast　dynamic　response　during　the　load　transient　verify　the　effectiveness　of　the　proposed　scheme.
