Pulse Generation Method for DC Self-balancing T-type Three-level Grid Connected Inverter
To solve the imbalance problem of DC voltage in three-level inverter, the relationship between output waveforms of a three-phase four-wire system and its trigger pulse was analyzed, and a pulse realization method based on DSP+FPGA controller was given. This paper analyzed the flow of energy during t...

| Summary: | To solve the imbalance problem of DC voltage in three-level inverter, the relationship between output waveforms of a three-phase four-wire system and its trigger pulse was analyzed, and a pulse realization method based on DSP+FPGA controller was given. This paper analyzed the flow of energy during the converting process and the root causes of DC voltage imbalance, and improved the method of pulse generation. Finally, the analysis results were verified on a three-phase four-wire APF platform. |
