Considering that almost 60 percent of total electric energy produced worldwide is used to run motors of every size, shape and efficiency, the adoption of variable speed drives can save as much as 70 percent of energy costs by controlling the speed of the load. New energy efficiency standards for compressors an

Many high power systems require the use of a hot-swap device to safely control of the inrush currents at powerup and provide fault protection. These circuits are commonly found in systems such as servers, network switches, redundant-array-of-independent-disk (RAID) storage, and other forms of communications infrastru
