Optimizing BLDC Motor Control Through System Simulation

Siddharth Mohan, Sr. Design Engineer, Qorvo

Why BLDC motors? Electric motors are responsible for roughly 50% of the world’s total electrical energy consumption, according to the European Commission1. Improving motor efficiency not only reduces operational costs but also plays a vital role in lowering global CO₂ emissions. Among available motor te

A new life for linear chargers

Steve Knoth, Linear Technology

Switchmode battery chargers are popular choices in applications due to their topology flexibility, multi-chemistry charging, high charging efficiencies which minimize heat to enable fast charge times and wide operating voltage ranges. Nevertheless, some downsides of switching chargers include relatively high co

SiC MOSFETs empower LED driver design

Marcelo Schupbach, PhD., Technical Marketing Manager, Cree, Inc

For high-bay and outdoor lighting fixtures, the cost of the LED driver electronics is reported to be 17% of the total fixture cost. An additional 40% of the fixture cost is contributed by the mechanical, thermal, and electrical portions of the fixture [1], which, in part, help support the weight and volume of th

Using Situational Intelligence

John Reed, Space-Time Insight

We expect utility services to be everywhere we are: charging our electronics in airports, flame-grilling our meals in restaurants, and filling drinking fountains in our public parks. To provide this level of service and convenience, utilities build networks of wires and pipes and communications channels th

Big Data needs efficient energy solutions

Michael Tryson and Erin Byrne, TE Connectivity

Big Data, a term that seems to encompass many of today’s technology buzzwords including the Internet of Things (IoT), machine to machine (M2M), wireless communication, cloud computing, and more is driving the need for increased bandwidth. Among the problems that became apparent even at 10Gbps is the power co
