Normally, the boost DC/DC circuit is the most common scheme to increase the output AC voltage of an inverter [ 3, 4, 5 ]. In [ 3 ], Gupta et al. adopted this scheme to increase the DC-link voltage, and proposed a stored energy modulation to reduce the required capacitance of the DC side.
First, a new boost inverter without inductors is put forward. Second, a corresponding modulation strategy is proposed to achieve capacitor voltage self-balancing and to regulate the output voltage. Third, a new scheme is given to extend the inverter and obtain a higher voltage gain. The remainder of this paper is organized as follows.
Thus, various boost-inverter topologies have been proposed to increase the DC-link voltage. Normally, the boost DC/DC circuit is the most common scheme to increase the output AC voltage of an inverter [ 3, 4, 5 ].
This converter offers advantages such as reduced count of switched capacitors and power devices, elimination of load-side filtering elements, reduced switching ripple in output voltage due to inherent interleaving, reduced voltage and current total harmonic distortion (THD), and lower ratings of the switched capacitors.
Switched capacitor–based inverters are emerging as a popular alternative to the conventional MLIs that do provide inherent charge balancing, reduced device stress, output voltage–boosting capability, and highly compact converters. This work proposes such a current-fed DC–AC switched capacitor converter (SCC).
The output voltage includes two voltage levels ( Vdc, 0), and the voltage reference is in subsector I. The voltages of both capacitors ( uca1 and uca2) are 86.9 V, which is close to the DC-source voltage (90 V).
