In the proposed inverter, similar to other switched capacitor multilevel inverters, charging and discharging the capacitors periodically occurs. During the charging process, losses are mainly due to the voltage ripple of the capacitors.
Provided by the Springer Nature SharedIt content-sharing initiative This paper proposed a hybrid switched-capacitor inverter to reduce the number of components and achieve automatic capacitor balancing. The proposed structure combines a switched capacitor (SC) unit with a flying capacitor (FC).
Therefore, the losses in switched capacitor multilevel inverters are categorized into three types: switching losses (P sw), ripple-induced losses (P rip), and conduction losses (P cond). According to Eq. (24), the total inverter losses are the sum of these three components.
Subsequently, a numerical comparison is made with recently proposed 13-level switched-capacitor inverters, demonstrating the advantages of reduced active components, simplified control, cost-effectiveness, and low power losses. Finally, simulation results are presented to confirm the performance of the proposed structure.
