A Novel Sensorless Voltage Multiplier Inverter for Electric Vehicle Application

Abstract

This article introduces a novel multilevel inverter with a reduced number of circuit components suitable for electric vehicle application. The proposed voltage multiplier converter can generate nine voltage levels twice the input DC one. This single-source inverter is also applicable for transferring the power generated by renewable energy sources to the power grid. The nearest level control strategy helps the operation of the topology. Self-voltage balancing ability of the circuit capacitors without using any sensors along its low number of circuit devices are the significant merits of this structure. Furthermore, a detailed survey of the operational requirements for comparing the proposed topology to the conventional ones is discussed in this paper. Additionally, the performance of the proposed topology is verified through both simulation and experimental results, reaching an efficiency of 94.74 percent for the intended operating point.
