Synopsis :  

This paper concentrates on the closed loop control scheme, focusing on the reduction of total harmonic distortion (THD) in a proposed seven level flying capacitor multilevel inverter (FCMLI). Among the various multilevel inverter (MLI) topologies, FCMLI provides more advantages. The development of closed loop model for seven level FCMLI dramatically reduces the low-order harmonics and THD. Extensive simulation has been applied to compare the performance of the proposed system in closed loop control scheme with that of the open loop control scheme. In order to justify the merits of the proposed system, it is interfaced with the single phase lamp load and analysed through simulation investigations.
