This paper introduces a nine-level (9L) boost inverter topology with reduced peak standing voltage (PSV) across the switches. The topology consists of a single DC source, two capacitors, a switched-capacitor (SC) and a floating capacitor (FC), and eleven power electronics switches. Due to the inherent voltage boosting capability, the proposed inverter is suitable for low-scale voltage applications such as photovoltaic (PV), fuel cell, and single battery-operated electric vehicles (EVs). A sensorless approach is introduced to stabilize the requisite voltage across the FC for any changes in input voltage. A generalized topology is also presented to obtain n-times voltage gain along with a high number of intermediate voltage levels. The PSV of the switches does not exceed the value of the input DC voltage, irrespective of increase in voltage gain. The results show that the voltage across the FC is unaffected by stepped variations in the modulation indices, power factor of load, pulse width modulation (PWM) techniques, and the operating frequency. Furthermore, when the input voltage changes, the voltage across the FC is automatically adjusted to a new requisite value within 0.6s. The topology works for a wide range of modulation indices (0–1) and loads. A thorough analysis is done to show that the proposed topology is superior to recent topologies.
