Figure 1: Conventional Intermediate Bus Architectures use a fixed-ratio isolated bus converter (IBC) to step down 48V to a 12V intermediate rail, which then feeds niPOL converters
AI processors can draw up to thousands of amps while operating at voltages well below 1V. This current demand is unprecedented and has turned the power delivery network (PDN) into a major system bottleneck.
With every amp pushed through PCB or substrate copper power planes, conductive losses and, thermal m
The implementation of 3-phase brush-less direct current (BLDC) motors is becoming increasingly widespread in contemporary automobile designs. There are now a multitude of different places inside the latest vehicles (from luxury right through to economy models) where they can be found - having proved themselves to
Once limited to simple devices like walking or running step counters, wearable devices have become more advanced seemingly overnight. From vibration-from-speech generating vests for the deaf, to Google Glass, to advanced fitness activity trackers, to night vision equipment, to heads-up imaging displays, wearable de
Despite the development of ultralow power integrated devices, the overall demand for power at a system level is only increasing. At the same time, OEMs remain under pressure to make their end-applications physically smaller, which continues to drive demand for smaller and more efficient power supplies.

When the first generation of silicon carbide (SiC) Schottky diodes was introduced more than 10 years ago, their widespread adoption was somewhat challenged by unforeseen dV/dt limitations within certain manufacturers’ devices. In particular, devices with lower dV/dt capability were susceptible to failure from larg
The longstanding worldwide trend in telecommunication has been away from fixed (wireline) service and towards wireless communication (see Figure 1). Meanwhile, as part of the convergence of tele- and data-communication, network traffic has been increasing by an order of magnitude roughly every four to five years. Fo
The explosion of Internet applications and data usage has put a great deal of pressure on servers and their related infrastructures. This massive growth of resources poses questions on energy demand to the major Internet providers and server makers, increasing the demand for more efficient energy utilization.

Advanced technologies are driving innovations in mobile healthcare delivery - exciting diagnostic and monitoring telehealth and eHealth devices that allow physicians to reach more people more efficiently, even in remote regions of the world. Optimal patient comfort and mobility depends on packaging more features in
