A method is presented to compute the switching angles in a multilevel converter so as to produce the required fundamental voltage while at the same time not generate higher order harmonics. Using a fundamental switching scheme, previous work has shown that this is possible only for specific ranges of the modulation index. Here it is shown for a three DC source multilevel inverter that, by modif...

This paper presents a micro controller based control of multilevel inverter for single phase Induction motor. IGBT is used as power element. Pulse width modulation techniques (PWM), introduced three decades ago, are the most used methods to control the voltage and frequency supplied to electrical AC machines.

A new multilevel inverter (MLI) topology is proposedusing a level doubling network (LDN). The LDN takes the form of a half-bridge inverter to almost double the number of output volt-age levels. The concept (of the proposed LDN) has the capability of self-balancing during positive and negative cycles without any closed-loop control/algorithm, and it does not consume or supply any power. The topo...

Power electronic converters are becoming more and more popular for various industrial applications. To overcome the limitation of semiconductors current and voltage ratings in high power applications, series and parallel connection of switches is often considered an effective solution. In addition, stepped waveform in the output of inverter has better harmonic spectrum than 2-level waveform in ...
