To　overcome　the　traditional　single-phase　current　mode　PWM　inverter＇s　inherent　defects　such　as　large　energy　storage　inductance,　large　energy　storage　inductance　current　and　serious　distortion　of　the　output　voltage　waveform,　the　single-phase　current　mode　PWM　inverter　of　one-cycle　control　strategy　with　limited　energy　storage　inductance　current　is　proposed　in　this　paper.　The　inverter　is　working　at　current　freewheeling　mode　when　the　energy　storage　inductance　current　is　above　the　limited　value　or　at　Boost　mode　when　it　is　below　the　limited　value　separately.　The　steady　principle　characteristics　of　this　kind　of　inverter　such　as　eight　operating　modes　in　one　low　frequency　output　cycle,　the　state　equations　of　the　switches,　and　the　high-frequency　operating　process　are　deeply　investigated.　And　the　main　design　criterias　for　the　key　circuit　parameters　such　as　the　voltage　transfer　ratio,　the　limited　value　of　the　energy　storage　inductance　current,　the　value　of　the　the　energy　storage　inductance,　the　input　and　output　filters,　and　the　voltage　and　current　stress　of　the　power　switches　are　derived.　Designed　and　developed　1　kVA　110　VDC/220　V　50　Hz　inverter　prototype　has　the　advantages　such　as　single-stage　boost　conversion,　high　conversion　efficiency,　high　quality　output　waveform,　low　energy　storage　inductance　etc.　The　correctness　and　advancement　of　the　proposed　research　scheme　and　theoretical　analysis　are　fully　confirmed,　and　effectively　overcomes　the　inherent　defects　of　the　traditional　single-phase　current　mode　PWM　inverter.　©,　2015,　The　editorial　office　of　Transaction　of　China　Electrotechnical　Society.　All　right　reserved.
