Thermal Topology Optimization of a Three-Layer Laminated Busbar for Power Converters

IEEE Transactions on Power Electronics, 2017
This paper focuses on a topology optimization method for laminated busbars in power converters that minimizes the quantity of copper used while keeping the temperature under the allowed limits. Busbars are widely studied for adding their stray inductance to the commutation loop, which causes surge voltage across the power devices. However, the study of

Correlation of degree of EVA crosslinking with formation and discharge of acetic acid in PV modules [PDF]

, 2017
Ethylene vinyl-acetate (EVA) encapsulated crystalline silicon PV modules see encapsulant related degradation such as the hydrolysis of EVA which leads to generation of acetic acid that corrodes cells and cell metallisation. The formation and discharge of

Liquid PV Module Encapsulation to Enable Circular Design

Progress in Photovoltaics: Research and Applications, EarlyView.
This study demonstrates a novel liquid encapsulation technology to enable circularity in c‐Si photovoltaic modules. The optical properties and power conversion efficiency of liquid encapsulation is similar to EVA encapsulation and better than air encapsulation.

Influence of Arc Faults on Pressure Production Characteristics in AC Turret of UHV Transformers

High Voltage, EarlyView.
ABSTRACT The overpressure caused by arc fault in the oil tank can lead to a transformer explosion. Since the AC turret of transformers serves to connect the transformer windings with the AC busbar, the arc current can be extremely high if an earth fault arc occurs leading to potentially hazardous pressure.

What Is a Polyolefin? A Critical Overview of Ethylene Copolymers Used as Solar Photovoltaic Module Encapsulants

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 4, Page 367-395, April 2026.
Polyolefin encapsulants are gaining dominance in PV modules, yet confusion persists around PO, POE, and TPO definitions. This study clarifies terminology, reviews materials, and properties and proposes a taxonomy to improve understanding, communication, and reliability in solar module manufacturing.
