摘要
This article proposes a novel single-source high step-up asymmetrical multilevel inverter (MLI) topology based on Marx generator configuration with voltage multiplying capability. The operating principles of the proposed converter (which is named Marxiplier) are completely different from the MLIs presented in the literature. Proposed converter uses a low-voltage dc source with high-frequency inverter (low-voltage ac input) and charges a series of capacitors multiple times of input voltage. These capacitors which work as asymmetrical sources can generate a high-amplitude ac output voltage with high number of levels. Another important aspect of this converter is producing negative levels in the output voltage without using a high-voltage full-bridge inverter and reducing the number of the components. MATLAB simulations and a laboratory test results of a 21-level prototype are employed in order to verify the proposed converter operation.
