This paper presents a new method to find the optimum switching angles in voltage source multilevel converters in order to minimize specific higher order harmonics and decrease the total harmonic distortion (THD) of their output voltage waveform. The output voltage waveform of inverter can either be in the form of staircase or PWM. In order to increase the degrees of freedom and elimination of m...

This paper considers the problem of designing a multilevel pulse width modulated waveform (PWM) with a prescribed harmonic content. Multilevel PWM design plays a major role in many diverse engineering disciplines. In power electronics, multilevel PWM design corresponds to determining the inverter switching times and levels for selective harmonic elimination and harmonic compensation. In mechatr...

Selective harmonic elimination (SHE) is a suitable pulse-width modulation (PWM) technique for some applications of modular multilevel converters (MMC) with lower number semiconductor submodules (SM). However, SHE can make it difficult to control circulating currents in the MMC. Moreover, MMC vulnerable SM switch failures that reduce its output power magnitude and quality. This paper proposes fa...

Algebraic algorithms are powerful methods in solving the selective harmonic elimination (SHE) problem, which can find all exact solutions without requirements of choosing initial values.
