Abstract

The boosting feature of switched capacitor-based multilevel inverter topologies has been highly recommended for photovoltaic-based applications. However, the main concern with these topologies is the voltage stress across the switches along with the power component count for a higher number of levels. In this paper, a new single-stage boost nine-level boost inverter (9LBI) topology has been proposed with a single floating capacitor unit that pertains to all of the mentioned concern. The proposed topology gives a voltage gain of two, while the voltage stresses across switches have been maintained to be equal to or less than the dc input supply. Phase disposition pulse width modulation (PD-PWM) and nearest level control pulse width modulation (NLC-PWM) techniques have been used for the control of the switches in the proposed topology. A comparative study of different similar topologies in terms of cost, efficiency, voltage stress, and component count sets the standard for the proposed topology. Different simulation and experimental results have been obtained to determine the workability of the proposed topology in different environments and operating conditions.
