In this paper, a single phase thirteen level inverter which suitable for renewable energy systems is proposed. To clamp the neutral point voltage and to attenuate the fluctuation of common mode voltage neutral-clamped inverter is used. As compared to conventional multilevel inverter, in sensorless multilevel inverter voltage balance is easily. Flying capacitor (FC) H-bridge is cascaded with neutral point- clamped inverter. The low frequency switches are connected across the dc-link which enables to generate a 13L waveform. The PWM controller which is embedded with a sensorless voltage control is responsible for regulating the FC voltage. As the levels increases the harmonics are reduced. The THD is compared and analysed. Simulation work for the proposed topology is carried out in MATLAB/Simulink.
