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.

Understanding the Critical Roles of Specialty Capacitors in Power Electronics

Posted by Jordan Yates on Jan 10, 2024 8:15:00 AM

Capacitors serve many crucial functions in power electronic circuits. Their ability to store electric charge makes them essential components for regulating and smoothing power flow. 

Many of these capacitors are standard fare, but a few play highly specialized, functional roles. To meet application-specific demands, these capacitors must be selected carefully based on function, size, and interoperability.

Understanding The Basics of Ceramic Coaxial Resonator Filters

Posted by Peter Matthews on Jan 5, 2024 3:02:49 PM

Before jumping into a discussion on ceramic coaxial resonators, it is important to understand what a resonator is and how these electrical components work. In general, a resonator is an essential component for constructing a bandpass filter since the resonator is what will allow specified frequencies, or bands of frequencies, to pass through the filter as shown in Figure 1.
