Summary: | This paper proposes a single-source boost multilevel inverter topology with inherent voltage balancing feature. The proposed topology is synthesized by a combination of the conventional boost converter and diode-capacitor voltage multiplier circuit (VMC). The diode-capacitor VMC is capable to solve the capacitor voltage balancing problem and step-up the input voltage to the required level of dc link voltage. The proposed converter can provide variable fractional voltage gain, which is a key requirement to achieve the maximum power point (MPP) in a photovoltaic application. Zero-voltage-switching is achieved for the high-frequency switch, which mitigates switching losses. A hardware prototype of the proposed seven-level inverter is developed and the results obtained from the experimental prototype are demonstrated to validate the performance of the proposed converter. |
