Based　on　the　principle　of　the　three　phase　voltage　source　PWM　rectifier,　firstly,　describes　the　topology　of　the　three-phase　VSR,　and　establishes　the　three-phase　VSR＇s　mathematical　model　based　on　the　three-phase　stationary　symmetric　coordinate　system　(a,b,c)　and　two-phase　synchronous　rotating　coordinate　system　(d,q);　then　analysis　the　three-phase　VSR＇s　control　strategy,　and　discusses　the　feedforward　decoupling　control　strategy　of　the　inner　current　loop,　the　outter　voltage　loop　control　strategy　and　the　Space　Vector　PWM　(SVPWM)　control　strategy.　Secondly,　builds　a　simulation　model,　simulates　it　in　Matlab\Simulink　environment.The　simulation　results　show　that　the　system　has　good　current　waveform　of　AC　side　current,　high　system　stability,　fast　dynamic　response　speed,　and　can　realize　two-way　flow　of　energy,　energy　feedback,　and　unit　power　factor　control.　©　(2013)　Trans　Tech　Publications,　Switzerland.
