A　novel　magnetically-coupled　energy　storage　inductor　boost　inverter　circuit　for　renewable　energy　and　the　dual-mode　control　strategy　with　instantaneous　value　feedback　of　output　voltage　are　proposed.　In-depth　research　and　analysis　on　the　circuit,　control　strategy,　voltage　transmission　characteristics,　etc.,　providing　the　parameter　design　method　of　magnetically-coupled　energy　storage　inductors　and　output　filter.　The　circuit　topology　is　cascaded　by　the　input　source　in,　the　input　filter　in,　a　single-phase　inverter　bridge　with　a　magnetically-coupled　energy　storage　inductor,　and　a　CL　filter;　The　control　strategy　serves　the　output　voltage　as　a　reference　to　achieve　the　switch　of　step-down　and　step-up　modes　smoothly.　The　simulation　results　of　a　1000　VA　100-200　VDC,　220　V　50　Hz　AC　inverter　show　that　the　proposed　inverter　can　realize　single-stage　boost　power　conversion,　which　can　adapt　to　resistive,　capacitive　and　inductive　loads,　has　high　power　density　and　low　output　waveform　distortion.　It　has　good　application　prospects　in　small　and　medium-capacity　single-phase　inverter　occasions　with　low　input　voltage.　©　2022　Polish　Academy　of　Sciences.　All　rights　reserved.
