Multilevel inverters offers eminent solutions to high voltage power applications due the association of several devices in a series configuration. In this paper, comparative investigation both 15 and 17 level cascaded h-bridge multi inverter with cross fed permanent magnet synchronous motor are presented by appropriate simulations mathematical analysis. Comparative analysis includes Inverter ou...

The output voltage of a Multilevel Inverter (MLI) can be controlled using various low and high frequency modulation strategy. Apart from meeting the load demand, strategy also tries to reduce harmonics present in waveform. In this paper, novel strategy, Variable Structure Nearest Level Modulation (VSNLM) has been proposed with objective Total Harmonic Distortion (THD) thus giving better quality...

Among multilevel inverter topologies, asymmetric Cascaded H-Bridge (CHB) inverters have higher output-voltage levels than symmetrical ones. However, asymmetric multilevel inverters need pre-stage isolated and floating DC power sources, which make the system complicated and bulky. This paper is focused on solving the problem by using a single-core (magnetically-coupled) multiple-output forward-f...
