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

Blog post from Knowles Precision Devices. Starvoy represents Knowles Precision Devices across Canada, for further information on their range of highly engineered Capacitors and Microwave to Millimeter Wave components for use in critical applications in military, medical, electric vehicle, and 5G market segments.

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.

As the shift to using SiC-based semiconductors continues, other board-level components, such as capacitors, must change as well. For example, as systems operate at higher frequencies, the capacitance needed decreases, leading to many instances where film capacitors can be replaced by ceramic capacitors.

Why You Need to Use Ceramic Capacitors with Your SiC Semiconductors

In general, ceramic capacitors are small and lightweight, making ceramic capacitors an ideal option for military applications where space and weight are at a premium. When using SiC semiconductors specifically, since the switching speeds are quite fast, high-frequency noise and voltage spikes will occur. Ceramic capacitors are needed to filter out this noise. And for high-frequency power supplies applications, ceramic capacitors are a preferred option because these components have a high self-resonant frequency, low equivalent series resistance (ESR), and high thermal stability.

Knowles Precision Devices: Your Military-Grade Ceramic Capacitor Experts

As a manufacturer of specialty ceramic capacitors, Knowles provide a variety of high-performance, high-reliability capacitors that are well-suited for military applications. At a basic level, they build all of their catalog and custom passive components to MIL-STD-883, a standard that “establishes uniform methods, controls, and procedures for testing microelectronic devices suitable for use within military and aerospace electronic systems.” We also hold the internationally recognized qualification for surface mount ceramic capacitors tested in accordance with the requirements of IECQ-CECC QC32100 as well as a variety of other quality certificates and approvals. For their high-reliability capacitors, they go above and beyond these quality standards and ensure components are burned-in at elevated voltage and temperature levels and are 100 percent electrically inspected to conform to strict performance criteria

Resonant Capacitors: Your Key to Building Stable and Reliable Wireless EV Charging Technology

Blog post from Knowles Precision Devices. Starvoy represents Knowles across Canada, for further information please reach out to our sales team.

As electric vehicle (EV) adoption for both consumer and commercial purposes rapidly grows, so does the need for a more widespread, and faster, charging infrastructure. While we’ve seen vast improvements in charging technology in the last few years, as additional regulations on combustion vehicles are implemented and reliance on EVs increases, further EV charging innovations are needed. Currently, wireless charging is the newest EV charging technology evolving.

Qorvo: How to Get Smaller, Smarter, More Reliable Power Management

In this industry, it can be easy to take power for granted. Easy, of course, until you don’t have it. Managing that vital resource is critical for systems to operate properly, and in a world that demands smaller, faster and smarter devices, it can be a real challenge. But what if a built-in power management device helped tackle that job? Qorvo’s Configurable Intelligent Power Solutions (ActiveCiPS™) devices help control, monitor and optimize power distribution and conversion in different systems with built-in intelligence and configurability.

In complex systems, or when a designer needs a more advanced or innovative power solution, it can be too expensive to use discrete components. Power Management Integrated Circuits (PMICs) integrate multiple voltage regulators and control circuits into a single chip. Today’s PMICs are flexible, allowing users to update default settings like output voltages, sequencing, fault thresholds and other parameters. As a result, PMICs are used in many small devices such as wearables, hearables and IoT (Internet of Things) devices – all thanks to their small size, high efficiency and low power consumption. These tiny, high-performance PMICs maximize system efficiency and performance while providing design flexibility and lowering the bill-of-materials cost.
