Carbon-based nonvolatile resistive memories are an emerging technology. Switching endurance remains a challenge in carbon memories based on tetrahedral amorphous carbon (ta-C). One way to counter this is by oxygenation to increase the repeatability of reversible switching. Here, we overview the current status of carbon memories. We then present a comparative study of oxygen-free and oxygenated carbon-based...
Short circuit tests at 18, 25, and 65000 A on combination motor starters with circuit breaker protection are discussed. The appropriate failure criteria from Underwriters' Laboratories (UL) high available fault standards are referenced. The specialized test equipment required to do these tests are mentioned. Characteristics of the combination starters are described as they relate to short-circuit...
