High-Density Power Modules Simplify and Downsize EV Power System Design

Greg Green, Director of Automotive Marketing, Vicor

The electrification of the automobile is presenting new challenges for power system designers in achieving the highest power density at the lowest weight possible, eliminating compromises in vehicle range and overall performance. Designers of power delivery networks (PDNs) are also tasked with designing safe, effici

Resistor Specifications And How To Interpret Them

Kory Schroeder, Director of Marketing & Product Engineering, Stackpole Electronics

Resistors are one of the simplest electronic components. However, the specifications typically shown on datasheets can be confusing, and are often misinterpreted. In this article we discuss the different performance characteristics, the test conditions, and how to interpret the test results. We discuss potential di

Power Protection Starts with Switches

Mike Bolduc, Global Marketing Manager, Industrial & Medical Segments, C&K

Electricity is the crux of modern society. Without it we couldn't power our factories, charge our gadgets, keep our medical equipment running or even keep food from spoiling. From lighting, communication, heating, cooling, motor control, and more, the fact of the matter is our world runs on electricity. While the breadt

Supercapacitors Come Of Age

Kunio Nomura, Product Manager - Capacitors, Murata

Within just a few years, devices that previously housed no electronics – let alone information processing capabilities – have become increasingly ‘smart’, joining the Internet of Things. To fully realisethe benefits of IoT, intelligent device performance levels and functionality have increased exponentially. Increased functiona

Intelligent Battery Monitoring

Steve Applegate, Sales Director, Stadium Stontronics

In our electrified world, we have become accustomed to continuity. If an airline scheduling system goes down due to a power outage or our electric vehicle runs out of charge unexpectedly, we’re outraged. Battery systems providing backup and motive power should have guaranteed availability; but how is this en

Functionality Convergence in IIoT

Muhammad Shafique, solution architect, Mentor a Siemens company

Today’s Industrial Internet of Things (IIoT) is rapidly changing how connected devices are enabled in modern heterogeneous multicore system-on-chip (SoC) architectures. These multicore environments reduce operational and maintenance costs by converging what were previously multiple discrete functions on a se

Implementing Tapped Buck Topology

Silvestro Fimiani, Product Marketing Manager, Power Integrations

When designing a medium power (10 W – 20 W), non-isolated, AC-DC power supply the choice is typically between a conventional buck topology and a more complex, flyback transformer based circuit. The buck converter design, although simple and easy to design with, has some drawbacks. Buck converters use a sim

Increasing the Power Density and Efficacy of Datacenters Using a Two-Stage Solution for 48V Power Distribution

Qian Ouyang, Rohan Samsi, and Jinghai Zhou, Monolithic Power Systems

Current datacenters typically have a 12V backplane and distribution on board and need to convert the voltage down to around 1V, which is usually achieved with a synchronous buck regulator, single- or multi-phase. The racks in these datacenters normally max out at a power rating of 20kW. There is a need in the in
