| Popis: | Aiming at the structure of the three-phase three-level current source inverter, a control method for realizing the five-level output of the inverter by changing the output current of the DC bus was proposed. The method was based on the five-level current source inverter modulation strategy, changed the current of DC bus and the switching state of the inverter through logic transformation to realize the five-level output of current source inverter without increasing the number of switching devices. The simulation results showed that this method could realize the five-level output of the three-phase three-level current source inverter and reduce the harmonic content of the inverter output. |
