  • Engineers develop self-healing muscle for robots
    Students recently unveiled their invention of a robotic actuator -- the 'muscle' that converts energy into a robot's physical movement -- that has the ability to detect punctures or pressure, heal the injury and repair its damage-detecting 'skin.'
  • EV battery recycling key to future lithium supplies
    Lightweight, powerful lithium-ion batteries are crucial for the transition to electric vehicles, and global demand for lithium is set to grow rapidly over the next 25 years. A new analysis looks at how new mining operations and battery recycling could meet that demand. Recycling could play a big role in easing supply constraints, the researchers […]
  • New chiral photonic device combines light manipulation with memory
    Engineers have developed a multifunctional, reconfigurable component for an optical computing system that could be a game changer in electronics.
  • Electric buses struggle in the cold, researchers find
    Researchers have released new insights on a pilot program involving all-electric buses in Ithaca, NY, USA -- with implications for cities, schools and other groups that are considering the electrification of their fleets, as well as operators, policymakers and manufacturers.
  • Cryogenic hydrogen storage and delivery system for next-generation aircraft
    Researchers have designed a liquid hydrogen storage and delivery system that could help make zero-emission aviation a reality. Their work outlines a scalable, integrated system that addresses several engineering challenges at once by enabling hydrogen to be used as a clean fuel and also as a built-in cooling medium for critical power systems aboard electric-powered […]
  • Nature-inspired breakthrough enables subatomic ferroelectric memory
    A research team has discovered ferroelectric phenomena occurring at a subatomic scale in the natural mineral Brownmillerite.

3 phase AC systems

In this article we take a closer look at the three phase power system. I will begin with giving you an overview of the differences between the two types of systems, namely the star connection and the delta connection. The sebsequent two sections will go more in-depth into the equations, ...
