Compared　with　carrier　based　sinusoidal　pulse　width　modulation　(SPWM),　space　vector　pulse　width　modulation　(SVPWM)　is　widely　used　because　of　its　higher　current　(voltage)　utilization　factor.　In　current　source　converter　(CSC),　SVPWM　technique　is　harder　to　achieve　than　voltage　source　converter　(VSC).　To　make　the　implementation　of　CSC　SVPWM　technique　easier,　this　paper　presents　an　indirect　PWM　method,　which　states　that　the　modulation　strategy　of　three　phase　CSC　can　be　got　from　those　used　in　three　phase　VSC　by　transforming　bi-logic　signals　to　tri-logic　signals.　In　contrast　to　existing　methods,　a　seven-segment　modulation　method　is　proposed.　The　presented　method　is　validated　by　simulations,　which　show　that　the　indirect　PWM　method　has　many　advantages　of　easy　implementation,　low　harmonic　of　AC　side　current,　and　low　ripples　of　DC　side　current,　etc.　©　2017　IEEE.
