Abstract
This paper proposes a novel topology, named the switched-capacitor-inductor active-switched boost inverter (SCL-ASBI), based on a switched boost inverter (SBI). The proposed SCL-ASBI allows a high voltage gain with fewer components used in the impedance network. It can be extended to an n-cell by adding one inductor, one diode, and two capacitors for further improving the boost capability. A comparative analysis between the proposed SCL-ASBI topology and four different topologies based on the SBI is presented. The closed-loop output voltage control scheme of the SCL-ASBI is suggested to linearly control the ac output voltage in a wide range. The extended-boost SCL-ASBI (EB/SCL-ASBI) topology, implemented by adding one cell to the SCL-ASBI, is introduced to achieve a higher voltage gain. Both the simulation studies and the experimental results obtained from a prototype built in the laboratory are carried out to verify the theoretical analysis and performance of the proposed topologies.
