| Abstract: | The Carrier Phase Shifted-Sinusoidal Pulse Width Modulation(CPS-SPWM) technique is an excellent modulation method with many good features as that the higher equivalent output carrier frequency can be obtained from lower switching frequency devices.This technique has been applied widely in multilevel Voltage-Source Inverter(VSI).In this study,the operation principle of three-phase multilevel Current-Source Inverter(CSI) is given.Based on the principle of CPS-SPWM technique,its feasibility in the multilevel CSI is proposed,and the implementation method is given.Lastly,an experimental system of a five-level CSI is built to validate the proposition. |
