摘要
This paper presents an innovative driver circuit for a new current regulator of the multilevel inverters. The proposed regulator has a PI controller to guarantee the optimum tracking for the reference current. This proposed regulator has the advantage of integration between the PI controller and the multicarrier switching operation. This regulator fits the operation of multilevel and cascaded converters. The suggested current regulator is compared with several existing current regulators of the multilevel and cascaded converters. The performance of the proposed regulator is verified using simulation results in comparison with the performance of the common existing current regulators for the multilevel inverter. Moreover, this paper shows the performance of the new regulator in power system applications.
