An analytical method of switching waveform design for selective harmonic elimination
Mathematics and Computers in Simulation, 2021Abstract The paper proposes an analytical approach to the design of switching waveforms to eliminate harmonics and thereby improve THD (Total Harmonic Distortion) in power converters. Generally, numerical solutions are used to obtain the switching angles to eliminate targeted harmonics and the solution requires guessing of an initial value and a ...

Design equations for selective harmonic elimination and microcontroller implementation
IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014The paper presents an analytical approach to find switching angles for an optimal PWM signal. The solution is in closed form that eliminates the need for numerical solution to find the transition angles. The disadvantage in iterative computation is overhead in computational effort as it requires a PC with expensive software and solution time can be a ...

Selective Harmonic Elimination for an Asymmetrical Multilevel Converter
2007 IEEE International Symposium on Industrial Electronics, 2007In this paper, a novel asymmetrical multilevel converter is proposed which is composed a 3-level leg and a 2-level leg. The principle of the converter is analyzed. The new schema requires fixed insulated supplies instead of capacitors. Selective harmonic elimination method is used to eliminate the specified harmonics in the output voltage.
