Automation is essential to efficiency and productivity in today’s fast-changing industrial scene. High automation unites warehouses, filling operations, rolling mills and conveyor belt systems. These systems monitor and collect data on temperatures, voltages and speeds using a complex network of sensors “in the field.” This vital data is sent across tens of meters of wires to a central control unit for crucial operation-optimization choices. This seemingly simple operation is complicated by the hostile industrial environment’s strong transient-voltage fluctuations and electromagnetic interference. Compact digital isolators may solve these issues and ensure data flow. In this issue, Timur Uludag, senior technical marketing manager at Würth Elektronik eiSos Group in the MagI3C Power Modules business unit, simplifies galvanic isolation and explains how it ensures data transmission in industrial intralogistics systems.
Moreover, in this issue, we analyze optical fiber probes and how they boost wide-bandgap power electronics development, a comparative analysis of conventional and SiC-based ANPC topologies based on thermal models and device losses, and a framework for wireless communication and power transfer in industrial IoT and hydrogen electric vehicles. Automakers are tackling various technological issues in vehicle electrification. Electronic designers and engineers of powertrain and high-voltage technology systems for a sustainable future want to increase EV range while decreasing design complexity and external component prices.
Modern automotive vision focuses on maximizing EV autonomy by minimizing complexity and design expenses. In this issue, we describe how SiC power electronic components, which improve system performance, greatly affect the EV ecosystem. SiC power devices find extensive utilization in various domains, including power supplies, battery EVs, power-conversion systems for battery charging and traction drives, industrial motor drives and renewable-energy–generation systems like solar and wind inverters.
Furthermore, an article will delve into the intricacies of a novel three-phase current-source rectifier (CSR) with an asymmetrical configuration, examining how it distinguishes itself from conventional CSR. This exploration will encompass the advantages and disadvantages of the proposed CSR in relation to power loss, output filtering, voltage stress and current stress. Analog Devices Inc.’s Erik Lamp, product applications engineer, and Xinyu Liang, application engineering manager, showcase the merits of utilizing the high-performance Silent Switcher 3 architecture. This architecture boasts remarkable attributes, such as ultra-low noise and rapid transient response, particularly in multiphase buck applications.
In today’s dynamic technological landscape, our world is witnessing groundbreaking innovations across various domains. From the imperative need for a capillary public charging infrastructure to accelerate the widespread adoption of EVs in urban areas to the revolutionary advancements in wireless EV charging and the transformative influence of quantum computing on industries like power electronics, other articles included in this issue explore the frontiers of innovation and their profound impact on our daily lives.
The challenges of Power for the electrification of vehicles
By Giordana Brescia
Efficient electric vehicles (EVs) design requires careful analysis of propulsion technology. Technological innovation is helping to make electric vehicles more accessible, safer, and energy-efficient, making sustainable transport an ever more tangible reality. The energy systems of the latest generation vehicles are moving towards greater electrification. EVs are characterized by high efficiency, limited space, small shape, and weight.
Therefore, their onboard energy technologies, such as power electronic converters and components, must be compact and lightweight. For this reason, the automotive and electronics industry has to face some important technical challenges for the progress of e-mobility: ultra-fast charging or while on the move, advanced battery technologies, energy conversion systems, etc.
Net-Zero Carbon Microgrid Infrastructure
By Abhishek Jadhav
The concept of microgrids involves combining various distributed energy resources, including energy generation, storage and loads, to enhance energy security and resilience. Microgrids have proven effective in ensuring a reliable energy supply during power disruptions caused by extreme weather events, cybersecurity attacks and equipment failures. They also offer a promising solution to address the challenges of climate change and move toward a carbon-free power system.
Net-zero carbon microgrids aim to achieve a balance between carbon emissions produced and carbon removed or offset within the microgrid’s boundaries. Their primary objective is to minimize or eliminate CO2 and other greenhouse gas emissions associated with electricity generation and energy consumption within the microgrid.
Sapphire Substrates Extend Voltage Range of GaN HEMT Devices
By Sonu Daryanani
Sapphire substrates have unique qualities, such as exceptional, low dielectric loss; electrical insulation; and optical transparency over a wide wavelength range. These characteristics have led to its wide use as a substrate in high-brightness (HB) LEDs using gallium nitride as the active semiconductor, as well as in microwave CMOS applications based on active silicon devices. In this article, we will discuss its use in GaN power devices.

Conductive Seals Help to Mitigate ESD Risks
By Maurizio Di Paolo Emilio
Conductive seals are materials that have been engineered specifically to maintain the mechanical integrity of a system while establishing a dependable electrical connection across a sealed interface. The principal purpose of this component is to impede the ingress of impurities, including grime, moisture and gases, while concurrently guaranteeing the uninterrupted flow of electrical impulses or power.
Honeywell to help decarbonize U.S. Virgin Islands with battery energy storage systems
Honeywell made the announcement that it will hand over its first batch of battery energy storage systems (BESS) to VIElectron, a CB Loranger Company. These BESS will be distributed to six solar parks that are strategically located throughout the United States Virgin Islands. As soon as they are finished, the solar array and BESS will satisfy thirty percent of the islands’ energy consumption through renewable sources, which will help the islands’ attempts to reduce their carbon footprint.
