Application of Stress-strength Interference Model in Failure Analysis of Power Semiconductor Device

Kongzhi Yu Xinxi Jishu, 2016
The direct reason of power semiconductor device failure from mechanical stress is that outside stress comes bigger than the strength of the device, which indirectly causes upload of electricity stress or heat stress and ultimately brings about failure of

High Voltage DC Active Current Injection to Simulate Geomagnetically Induced Currents in New Zealand

Space Weather, Volume 24, Issue 3, March 2026.
Abstract This study investigates the effects of geomagnetically induced currents (GIC) on New Zealand's electrical infrastructure via an intentional ground injection of direct current (DC) from a high voltage DC converter station. GIC manifests as quasi‐DC currents within power systems, potentially causing transformer saturation, increased reactive ...

A Hybrid Ultra‐High Voltage DC Transformer With Digital Twin‐Driven Operation and Control

Digital Twins and Applications, Volume 3, Issue 1, January/December 2026.
This study introduces a digital twin‐driven hybrid ultra‐high‐voltage DC transformer (UHVDCT) that combines high‐capacity LCCs with low‐capacity MMCs at the UHV side. This innovative topology reduces MMC requirements by 32.9% while ensuring stable power flow and dynamic reactive balance through real‐time virtual‐physical synchronization.

Modified‐Source Intrinsic Bulk Nanoscale Planar MOSFET

Electronics Letters, Volume 62, Issue 1, January/December 2026.
The modified‐source MOSFET (MS‐MOSFET) is an intrinsic bulk planar MOSFET to operate in nanoscale range. Due to the simple structure of this novel device, it can be fabricated using low‐cost CMOS technology. As FinFETs entail a complex and expensive structure, the concept of the modified‐source transistor presents a promising approach for cost ...

A Layered Composite Control Strategy for Voltage Source PWM Rectifiers Based on Improved Sliding Mode and Back‐Propagation Neural Network PID

Electronics Letters, Volume 62, Issue 1, January/December 2026.
To address the poor dynamic response and limited disturbance rejection of conventional dual‐loop PI control in three‐phase voltage source PWM rectifiers (VSRs), this paper proposes a composite control strategy featuring an improved sliding mode control (SMC) for the voltage outer‐loop and a back‐propagation neural network (BP‐PID) controller for the ...

Research on Voltage Regulation Methods for Flexible On‐Load Tap‐Changing Transformers

Electrical Materials and Applications, Volume 3, Issue 1, January/December 2026.
The control system determines whether the output voltage magnitude of the voltage source converter (VSC) is high, low or constant and generates the corresponding pulse signals. Each pulse is generated at the valve‐triggering instant, with its width corresponding to the commutation angle.
