Assessment of a Reconstructed Modulation Strategy for Energy Balance in Multilevel Cascade Inverters Varying the Modulation Index

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
This article presents an analysis of the reconstructed modulators modulation strategy, a technique designed for energy balancing in DC‐to‐AC converters. The study evaluates the performance of this strategy, applied to a seven‐level multilevel cascade inverter. ABSTRACT This paper presents an experimental evaluation of a PWM modulation strategy based on

Offline Pulse Distribution Strategies for SWISS Rectifier Using Improved PDM at High Switching Frequencies

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
This paper proposes an improved offline pulse density modulation strategy for the SWISS rectifier to achieve low input current distortion and high power factor at high switching frequencies. Experimental results at 38.4 kHz reduce THDi from over 30% to ≈10%, while high‐frequency simulations at 172.8 kHz achieve THDi of 3.3% and PF = 0.9954.

Design and Performance Analysis of BCH Codes Construction Over Eisenstein Local Rings Zpsω

Journal of Mathematics, Volume 2026, Issue 1, 2026.
A systematic study of BCH codes construction over Eisenstein local rings Zpsω for p ≡ 2(mod3), giving novel structural information to the coding theory, is known as a systematic code study. The rate of code learning, the error‐adjusting program’s potential, and the number of words in the code words are the key factors in determining how well the codes ...
