    A Switched-Capacitor Based Nine-level Boost Inverter Circuit for Mining Applications
    (Institute of Electrical and Electronics Engineers Inc., 2022) Prudhvi Krishna, B.N.V.V.; Kunar, B.M.; Murthy, C.S.N.
    A dual boost nine-level inverter for mining applications is proposed in this work. Capacitors are used as virtual sources to boost the voltage magnitude and increase the levels. Additionally, the proposed MLI circuit inherits benefits such as self-balancing capacitors, less blocking voltage, and fewer components. A simple PD-PWM scheme is used to generate gating signals. Circuit portrayal, operating principle, modulation, and capacitor voltage ripples are studied. MATLAB software is used to carry out simulations, and the obtained outcomes prove the boosting ability under different loading circumstances. A detailed comparative review is conducted with other recent SCMLIs to illustrate the superiorities of the proposed circuit. © 2022 IEEE.
