FPGA implementation of SHEPWM gate signal IGBTs
2018 7th International Conference on Systems and Control (ICSC), 2018This paper deals the generation of all signal gates for three-level inverter using FPGA SPARTAN-3E device. The PWM switching angles are computed on the basis of the selective harmonics elimination for several frequency values. In order to cancel three odd harmonics the arm voltage waveform profile contains four switching angles.

SHEPWM-Based Dead-Zone Control for PMSM under Low Switching Frequency
2023 5th Asia Energy and Electrical Engineering Symposium (AEEES), 2023Nowadays, permanent magnet synchronous motor (PMSM) has attracted extensive attention because of the high power density, high torque inertia ratio, etc., but PMSM presents poor performance under low switching frequency. Selective harmonic elimination pulse width modulation (SHEPWM) can eliminate low-order harmonics precisely under the low switching ...

Selective harmonics elimination PWM (SHEPWM) using Differential Evolution approach
2010 Joint International Conference on Power Electronics, Drives and Energy Systems & 2010 Power India, 2010This paper proposes the application of Differential Evolution (DE) algorithm to the selective harmonics elimination pulse-width modulation (SHE-PWM) scheme. The aim is to solve for the set of transcendental equations that determine the switching angles of the SHE-PWM waveform.

Inner Relationship Between SHEPWM and SVPWM in Tri-level Converter
2019 14th IEEE Conference on Industrial Electronics and Applications (ICIEA), 2019In this paper, a new selected harmonic elimination pulse width modulation (SHEPWM) of the tri-level NPC converter was studied by using improved initial value method, in which impulse was equal and center of gravity was coincidence. The multiple-solutions were obtained within the range of the whole modulation degree.

Shaft voltage suppression for inverter-driven induction motor applying SHEPWM
2008 IEEE Vehicle Power and Propulsion Conference, 2008In order to reduce the common mode (CM) voltage and shaft voltage for induction motor driven by inverter, an Improved Selective Harmonics Elimination Pulse Width Modulation (ISHEPWM) method was proposed in this paper. First ISHEPWM eliminates certain low order components of common mode voltage (CMV) generated by inverter.

SHEPWM Class-D Amplifier with a Reconfigurable Gate Driver Integrated Circuit
2021 IEEE International Symposium on Circuits and Systems (ISCAS), 2021A selective harmonic elimination pulse width modulation (SHEPWM) class-D amplifier (CDA) with a reconfigurable gate driver integrated circuit (IC) is proposed. The H-bridge CDA generates a three-level SHEPWM signal and cancels lower order harmonics of the switching voltage. To generate accurate pulses at the right switching angles, GaN devices are used
