This article presents a boost inverter scheme for higher-level output that involves input voltage boosting. The proposed topology can be reconfigured to produce 9 and 13 levels of output voltage with alternative topologies and a voltage gain of four or three, respectively.
The SC inverter in Ref. and the proposed inverter can achieve both purposes, but the diodes are unavoidable, resulting in higher conduction loss and a higher voltage stress in Ref. . The proposed three-level inverter can boost output voltage, has self-balanced capacitor voltage, and lower voltage stress, and the inverter has no diodes.
The most recent advancement in switched-capacitor boost inverters for high-frequency ac systems and solar PV utilization is their reduced component count. SC-based multilevel inverters (MLIs) are the ideal solution for PV applications since they have a larger voltage gain and a sensorless mechanism for self-voltage balancing.
In this paper, considering the nature of switched-capacitor inverters and their primary challenges, an 11-level structure with a boost factor of 2.5, along with reduced voltage and current stress, is proposed. This structure requires a single voltage source, 10 switches, 3 capacitors, and 2 diodes.
