Hybrid PWM on the Basis of SVPWM and SHEPWM for VSI as Part of 3L-BtB-NPC Converter
IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017The purpose of the research is to develop and study Hybrid PWM for three level back-to-back neutral-point clamped converter (3L-BtB-NPC) based on active front-end rectifier and voltage source inverter. Hybrid PWM must provide smooth switching between the algorithms of space vector PWM and selective harmonic elimination PWM of VSI.

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.
