ABB and IO have agreed to partner in the development of a new data center module based on direct current (DC) power to meet increasing demand for DC data centers. DC-powered technology is being increasingly adopted for electrical distribution in data centers as it reduces power conversion losses and is 10 to 20 percent more energy efficient than traditional alternating current … [Read more...]
Thermal Design Challenges in Automotive Alternator Power Electronics
Ever since the advent of the automotive alternator, or claw-pole alternating current generator, in the 1960's, there has been an ever-increasing thermal design challenge to cool the power electronics in these machines. Figure 1 depicts a typical cutaway section of a modern day alternator. At first glance one may think that cooling the diodes in a rectifier bridge of an … [Read more...]
