A　Flyback　mode　inverter　adopting　compound　control　strategy　which　combines　feedforward,　proportional　integral　and　repetitive　control　was　proposed.　The　circuit　topology,　operating　mode,　control　strategy,　system　stability,　controller　and　the　design　criteria　for　key　circuit　parameters　were　fully　investigated,　and　important　conclusions　were　obtained.　The　circuit　topology　is　composed　of　two　bi-directional　Flyback　DC-DC　choppers　with　their　inputs　connected　in　parallel　and　outputs　reversely　connected　in　series.　The　choppers　share　the　input　and　output　filters.　Repetitive　control　accumulates　the　errors　of　past　several　line　cycle.　The　control　value　of　current　cycle　was　obtained,　and　the　output　voltage　was　regulated　cycle　by　cycle.　The　designed　and　developed　1kVA　260VDC/　220V50HzAC　prototype　of　the　compound　controlled　Flyback　mode　inverter　has　excellent　performances　such　as　single　stage　power　conversion,　high　output　steady　precision,　fast　transient　responses,　high　quality　of　output　waveforms,　strong　load　adaptability,　high　conversion　efficiency　and　high　reliability,　etc.　©　2018,　Harbin　University　of　Science　and　Technology　Publication.　All　right　reserved.
