Effect of PWM schemes on the performance and common-mode current of the proposed modified seven-level H-bridge inverter

In this paper, modified H-bridge seven-level inverter topology is proposed. The performance of the proposed topology is evaluated in terms of the THD and the fundamental component of the output voltage for open-loop operation and in terms of common mode current for the connected grid system.
