Abstract : A multilevel inverter can generate a staircase waveform which has a reduced harmonic distortion. However, a high number of levels introduce the voltage imbalance problem. This paper presents a single-phase multilevel inverter topology employing coupled inductors which can output a five-level voltage. Only one dc voltage source is needed and the split of the dc voltage capacitor is also avoided, which eliminates the problem of dc capacitor voltage balancing with the conventional topologies. Six power switches with the same voltage stress and only one set of coupled inductors are adopted. Due to the reduced number of switches, losses will be less compared to the other topologies. Based on the possible switching patterns, pulse-width modulation technique is adopted for this inverter. The simulation results of the presented inverter using MATLAB is also discussed in the paper.
