18-Pulse Rectifier with Electronic Phase Shifting and Pulse Width Modulation [PDF]

open access: yes2018 IEEE 3rd International Conference on Intelligent Energy and Power Systems (IEPS), 2018
At present, 12-pulse rectifiers with electronic phase shift are known. Unlike classic rectifiers, they do not use phase-shifting transformers and have a unit power factor. Increasing of the rectifier’s pulse makes it possible to improve the harmonic composition of the input current.

Phase-shifted Discontinuous Pulse-Width Modulation Methods for Multi-level Inverters Operated in Over-modulation Range

Electric Power Components and Systems, 2014
AbstractThis article presents combinations of the generic phase-shifted pulse-width modulation method with conventional discontinuous pulse-width modulation methods operated in the over-modulation range. The treated discontinuous methods are the third harmonic injection, Depenbrock's DPWM1, and Ogasawara's DPWM2.

Performance Analysis of Five-Phase NPC MLI with Phase Shifting Carrier Pulse Width Modulation

ECS Transactions, 2022
The five-phase loads with Multi-Level Inverters (MLI) are preferred by industries in high and medium power applications due to lower switching loss, voltage stress across switches, etc. The controlling of a five-phase motor drive is done by Pulse Width Modulation (PWM) techniques.

Phase-shift selective harmonic elimination pulse width modulation for multilevel converter

2015 34th Chinese Control Conference (CCC), 2015
This paper propose a phase-shift selective harmonic elimination pulse width modulation(PS-SHEPWM) strategy for multilevel converter. Firstly, the two level SHEPWM (Selective Harmonic Eliminated Pulse Width Modulation) equations are solved by using the groebner bases method, and a group of harmonics will be eliminated from the resultant two level PWM ...
