Microgrid Integration in Smart Low-Voltage Distribution Systems

June 20, 2022 by Ramanuja Panigrahi; Santanu K. Mishra; Suresh C. Srivastava; Prasad Enjeti

Smart low-voltage distribution system (LVDS) is an essential component in realizing smart electricity grids. In countries like India and other energy-deprived regions of the world, researchers are looking for a holistic approach to integrate millions of small Renewable-powered homes in the LVDS and make the system smart. Restructuring the existing distribution system to form … [Read more...] about Microgrid Integration in Smart Low-Voltage Distribution Systems

White Hot: Is Your Power Supply Hacker Proof?

December 1, 2021 by Robert V. White

It is a sad fact that our digital connected world is under constant attack from malicious parties. Most of the time those bad actors are trying to steal money through fraud or extortion (ransomware attacks). Some of those malicious actors though have a bigger goal of attacking or terrorizing a nation by disrupting or crippling critical infrastructure such as power generation, … [Read more...] about White Hot: Is Your Power Supply Hacker Proof?

Practical Considerations for Design and Layout of High Power Digital PCBs: Reliably Powering Complex Multilayer Digital Printed Circuit Boards

June 1, 2021 by Mikhail Guz

This article discusses practical aspects of powering complex multilayer digital printed circuit boards (PCBs) from high-energy sources and tradeoffs that are required to make functional and reliable boards. What can be found between two layers of copper in a multi- layer PCB? Most engineers would say dielectric or isolation. Evidently not only that but, according to … [Read more...] about Practical Considerations for Design and Layout of High Power Digital PCBs: Reliably Powering Complex Multilayer Digital Printed Circuit Boards

A technology revolution is unfolding around us as every major mode of transportation is in some stage of electrification, whether on land, sea, or in the air. All of these transportation modes depend on electric machines that play critical roles in both propulsion systems as well as in a wide variety of accessory equipment. Fuel economy and reduced emissions of greenhouse gases and other pollutants are major driving forces for electrified transportation. Despite the significant differences between these varied transportation modes, they all share strong motivations to make their electric machines and adjustable-speed drives smaller, lighter, and more efficient. An excellent example of this trend for the power electronic drives is provided by comparing the drive units in the Tesla S (2012) and Tesla 3 (2017). As shown in the side-by-side views provided in Figure 1, the drive unit shrank in size from an enclosure that matched the size of its main traction motor to a much smaller unit that, at first sight, appears to be a non-descript end-bell attached to one end of the motor. Rather than focusing here on how this impressive reduction in mass and volume was achieved (addressed later in this article), the key point here is that similar technology trends are under way in many of the other transportation modes as well, making electrified transportation increasingly appealing and competitive in the process.
