A Passive LC Filter Based Harmonic Compensation for Multilevel Cascaded Inverters under Unbalanced DC Sources Using NVM Control Technique

Abstract


This work proposes passive lc filter network based multilevel cascaded inverters with beating width-modulation action to accomplish counterbalanced line-to-line achievement voltages and to aerate the modulation basis in the beeline modulation ambit area the achievement voltage can be linearly adapted in the multilevel cascaded inverter (MLCI) operating beneath asymmetric dc-link conditions. A neural voltage modulation action is proposed to accomplish achievement voltage acclimation as able-bodied as to extend the beeline modulation ambit up to the best attainable point in theory. In the proposed method, too ample of a dc-link alterity precludes the acclimation of the achievement voltages. The simulations for a seven-level phase-shifted articulate MLCI for electric car absorption motor drive appearance that the proposed adjustment is able to antithesis line-to-line achievement voltages as able-bodied as to aerate the beeline modulation ambit beneath the asymmetric dc-link conditions.
