Dual　buck　half　bridge　inverter(DBHBI)　has　a　benefit　of　no　shoot-through　issue,　however,　severe　waveform　distortion　is　badly　undesirable.　Hysteresis　control　is　commonly　used　to　improve　output　quality,　which　has　fast　dynamic　response　and　easy　to　approach.　Since　the　switching　frequency　in　the　hysteresis　control　is　unfixed,　voltage　loss　and　harmonic　frequency　issues　are　inevitable.　The　paper　proposes　a　novel　hybrid　sine　pulse　width　modulation　control　strategy.　When　the　inductor　current　is　greater　than　the　critical　inductor　current,　DBHBI　is　switched　to　the　half-cycle　SPWM　mode,　otherwise,　to　the　full-cycle　SPWM　mode.　Besides,　nonlinear　relationship　between　input　and　output　is　optimized　to　linear　relationship　which　facilitates　the　controller.　In　addition,　the　influences　of　the　mode　transition　are　discussed,　and　control　methods　to　solve　distortion　problems　under　different　traditions　are　proposed.　Finally,　simulation　and　experiment　results　demonstrate　the　superior　performance　of　implemented　strategy　on　waveform　improvement.　©　2017　IEEE.
