Examining Trends in Power Electronics

Posted by Peter Matthews on Feb 21, 2024 8:15:00 AM

At Knowles, it is our mission to provide specialty components that meet even the toughest performance and reliability requirements, especially for applications where failure is not an option. But, markets and requirements are constantly changing, which means we must closely monitor the trends impacting all the industries and applications where you might find our components. One area where we are seeing rapid innovation spanning the industries we serve is power electronics. At a high level, the trends driving power electronics innovation are largely centered around methods for providing more energy more efficiently while using smaller components. Below are four key power electronics trends we are currently monitoring and a how we can help you stay on top of each trend with your designs.

Power Divider Basics

Posted by Peter Matthews on Oct 25, 2023 8:15:00 AM

Radio frequency (RF) power dividers are designed to split an incoming signal into multiple outputs such that there’s a portion of the original signal’s power in each output. Given their critical function, power dividers play a particularly important role in antenna systems, telecommunications, and signal processing.

How Gallium Nitride (GaN) Semiconductors in Defense Power Supplies Affect Capacitor Selection

Posted by Jordan Yates on Oct 18, 2023 8:30:00 AM

Defense applications tend to operate at high voltages and wide temperature ranges. They require components with increased efficiency, reduced size, and high power density. Because a wideband gap (WBG) semiconductor embodies these characteristics, defense and aerospace systems are increasingly using Gallium Nitride (GaN) for power conversion.

Introducing the MD Series of Medical-Grade Capacitors for Implantable Device Design

Posted by Victor Lu on Aug 30, 2023 8:30:00 AM

A medical device is considered “implantable” if it’s partly or totally introduced into the human body via surgery or another medical intervention, and it’s intended to stay there for a long period of time. According to the American Medical Association (AMA), approximately 10 percent of Americans will receive an implantable device during their lifetimes. To serve consistent, often life-sustaining functions, implantables require high-reliability components that guarantee long-term performance.

How The Shift to SiC-Based Semiconductors in Military Power Supplies Affects Capacitor Selection

Posted by Jordan Yates on May 31, 2023 8:45:00 AM

To protect people and critical equipment, military-grade electronic devices must be designed to function reliably while operating in incredibly harsh environments. Therefore, instead of continuing to use traditional silicon semiconductors, in recent years, electronic device designers have started to use wide band-gap (WBG) materials such as silicon carbide (SiC) to develop the semiconductors required for military device power supplies. In general, WBG materials can operate at much higher voltages, have better thermal characteristics, and can perform switching at much higher frequencies. Therefore, SiC-based semiconductors provide superior performance compared to silicon, including higher power efficiency, higher switching frequency, and higher temperature resistance as shown in Figure 1.
