Ultra High Step‐Up Soft Switching Converter Based on the Interleaved Structure

open access: yesEnergy Science &Engineering, Volume 14, Issue 1, Page 540-556, January 2026.
The proposed topology provides high voltage gain and enhanced efficiency at low duty cycles, thereby reducing conduction losses in the switches. Its interleaved structure ensures current sharing, while the switches experience both low voltage and low current stress, further decreasing conduction losses.

Entanglement in Quantum Systems Based on Directed Graphs

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 1, January 2026.
The entanglement properties of quantum states associated with directed graphs are investigated. It is proved that the vertex degree distribution fully determines this entanglement measure, which remains invariant under vertex relabeling, thereby highlighting its topological character.

A Five‐Level Active Neutral‐Point‐Clamped Auxiliary Inverter Based on Reverse Blocking IGBT in Metro Applications

open access: yesIET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
We propose a novel five‐level active‐neutral‐point‐clamped converter utilising reverse blocking IGBT (RB‐IGBT). The inverter configuration significantly reduces conduction losses, as only two switches are on the current paths in some switching states. We also propose an optimised state machine‐based modulation strategy.

Real‐Time Implementation of Finite Control Set Model Predictive Control for BLDC Motors With Dynamic Speed References on ESP32

open access: yesIET Power Electronics, Volume 19, Issue 1, January/December 2026.
This paper investigates the application of Finite Control Set Model Predictive Control (FCS‐MPC) for Brushless DC (BLDC) motor speed regulation under dynamic references, including sinusoidal, square, triangular, and sawtooth signals. A novel cost function is introduced to evaluate switching frequency effects, and the influence of different weighting ...

PWM Dead Times in Automotive Traction Inverters using IGBT, SiC MOSFET, or Si/SiC Fusion Switch Power Modules

open access: yesIET Power Electronics, Volume 19, Issue 1, January/December 2026.
This article features a comprehensive methodology for analyzing and optimizing PWM dead time in automotive traction inverters, applicable to a wide range of power devices, including Si IGBT/Diodes, SiC MOSFETs, and Si/SiC Fusion switches. The proposed methodology enables a systematic comparison of dead time characteristics, focusing on part‐to‐part ...
