Virtual space vector modulation strategy for common‐mode voltage reduction in three‐phase three‐level flying‐capacitor split‐source inverters

Abstract: Transformerless systems play an important role in many applications, such as photovoltaic generation systems and motor drives, since they present reduced size and high efficiency. On the other hand, the flying‐capacitor split‐source inverter (FC‐SSI) merges the boost and the inverter stage in a single power conversion system. It is important to point out that conventional modulation strategies applied to the FC‐SSI can result in unacceptable common‐mode voltage (CMV) which is one of the main causes of leakage … Show more
