Figure 1: Replacing conventional, discrete power conversion with power modules throughout the vehicle provides significant cost and weight savings in EVs

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

Designing Batteryless Devices for Industrial and IoT Applications

Scott Soong, CEO, Pervasive Displays

The IoT has a battery problem. IoT implementations require large numbers of small devices deployed in areas without easy access to mains power. These devices therefore need to be low power and battery powered. But battery-powered devices present challenges. Batteries need to be recharged or replaced regularly, an

Balancing energy efficiency and ease-of-use in a world of high power demands

Dr. Stefan Gamerith: Senior Expert Product Marketing & Tamara Krappinger: Product Marketing Manager / MSc.

We are surrounded by electrically powered devices. The mobile phones in our pockets, the laptop computers we use on the job, the television in our living rooms, the servers powering the Internet, or even the EV car in our garage - all require electricity to operate and drive the demand for power supplies which ar

Power quality monitoring technology - helping industrial equipment stay healthy

Chandrappa Niranjan & Banerjee Swarnab , Analog Devices

According to a recent study published by the Electric Power Research Institute (EPRI), large industrial facilities in the US lose over $100 billion every year due to power problems including power supply variations and voltage disturbances. When the lights flicker at home, it’s an annoyance. But when po

Avoiding Voltage Rail Blind Spots

Bruce Haug Sr. Product Marketing Engineer, Power Products, Linear Technology Corporation

Knowing the condition and operating status of a voltage regulator is perhaps the last remaining blind spots in today’s modern electronic systems since they do not normally have the means for directly configuring or remotely monitoring key operating parameters. It’s usually critical for reliable operation wh

Unleashing SiC MOSFETs to Extract their Maximum Performance in Power Converter Designs

Xuning Zhang, Principal Application Engineer & Levi Gant, Application Engineer Monolith Semiconductor, Inc.

Silicon carbide (SiC) MOSFETs switch up to five to ten times faster than silicon (Si) IGBTs and can operate at higher junction temperatures. Because they can switch on and off so quickly, they enable higher switching frequencies and therefore allow those designing inverters and other power converters to shrink th

A new motor control platform designed by Intel & their partner D3

A Single-Chip FPGA-based Platform for Integrated Power and Motion Control

Mark Frost and Ben Jeppesen, Intel Programmable Solutions Group

Motor control applications using small fast-spinning motors such as e-turbos, UAVs, surgical instruments and high-speed pumps, and the advent of SiC and GaN switching transistors, are driving a need for compact drives with high-frequency control loop updates. This paper describes a multi-axis motor and power co
