Harmonic minimization in multilevel inverters using selective harmonic elimination PWM technique
2013 International Conference on Renewable Energy and Sustainable Energy (ICRESE), 2013Generally the output voltage of the inverters must be sinusoidal. However the waveforms of practical inverters are non sinusoidal and contain certain harmonics. For low and medium power applications, square wave or quasi square wave may be acceptable but for high power applications, low distorted sinusoidal waveforms are required.

Selective harmonics elimination: PWM method versus optimized total harmonic distortion
4th International Conference on Power Engineering, Energy and Electrical Drives, 2013This paper describes two different PWM methods to improve the quality of the output voltage waveform provided from five level inverter. The first one is the selective harmonics elimination (SHEPWM). The purpose is to cancel the 5th, 7th and 11th harmonic row.

The Selected Harmonic Elimination PWM Strategy Based on FPGA
2016In the electric traction transmission system, subject to the maximum switching frequency and output voltage and current harmonic performance, a special optimized pulse width modulation strategy is generally required. The selected harmonic elimination PWM eliminates the lower-order harmonics so the interference of motor torque will decrease.

Selective harmonic elimination for a NPC converter using modified carrier signals
IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014The Selective Harmonic Elimination (SHE) modulation scheme is a very useful method to eliminate some lower harmonics of the output signals in a NPC converter, but as it is an offline method its implementation in a system sometimes is very hard to do. Instead of use the SHE modulation, in this paper it is proposed an approximation of the SHE scheme to a

Genetic Algorithm for Selective Harmonic Elimination PWM Control
2014The paper presents an optimal solution for eliminating pre-specified order of harmonics from three-phase inverter. One solution to this problem is the selective harmonic elimination, which is required to solve multiple nonlinear equations simultaneously. Genetic algorithm (GA) technique is introduced to minimize the computational burden associated with

The most prominent issue relevant to the initiative multi-level inverters is how to provide a high-step staircase quasi-sinusoidal voltage against low switch numbers. This paper presents an innovative asymmetrical multi-level inverter structured by cascaded sub-multi-level inverter bonded to H-bridge inverter to unravel aforesaid issue.
