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](https://blog.knowlescapacitors.com/blog/high-performance-capacitors-to-meet-the-needs-of-demanding-aerospace-and-defense-applications). 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.

Therefore, to meet both capacitance demands and size requirements, electronic designers simply cannot continue to add more capacitors. While capacitor stacking is an option, many stacked assemblies are still quite large and stacking often introduces new failure modes, such as piezo electric cracking (Figure 1).  [Read More](https://blog.knowlescapacitors.com/blog/the-capabilities-benefits-and-key-applications-for-stackicap) 0 Comments [Click here to read/write comments](https://blog.knowlescapacitors.com/blog/the-capabilities-benefits-and-key-applications-for-stackicap#comments-listing) Topics: [Capacitor](https://blog.knowlescapacitors.com/blog/tag/capacitor) ## [Why Bidirectional Charging for EVs Requires Special Attention to Design](https://blog.knowlescapacitors.com/blog/why-bidirectional-charging-for-evs-requires-special-attention-to-design) Posted by [Jordan Yates](https://blog.knowlescapacitors.com/blog/author/jordan-yates) on May 10, 2023 8:45:00 AM - [Tweet](https://twitter.com/share) [![Why Bidirectional Charging for EVs Requires Special Attention to Design](https://blog.knowlescapacitors.com/hubfs/Bidirectional%20Charging%20Knowles%20Preview%20Image2.png)](https://blog.knowlescapacitors.com/blog/why-bidirectional-charging-for-evs-requires-special-attention-to-design) As interest and adoption increase in the electric vehicle (EV) arena, associated technologies are advancing quickly.

Since this involves removing the DC component and allowing only the high-frequency AC component to pass or bypass, this can be a complicated process. The blocking capacitor needs to present a near reflectionless transition at the frequency the line is seeing and at a bandwidth that allows the entire signal to pass without degradation.  [Read More](https://blog.knowlescapacitors.com/blog/the-advantages-of-knowles-precision-devices-broadband-capacitors) 0 Comments [Click here to read/write comments](https://blog.knowlescapacitors.com/blog/the-advantages-of-knowles-precision-devices-broadband-capacitors#comments-listing) Topics: [Capacitor](https://blog.knowlescapacitors.com/blog/tag/capacitor) ## [Capacitor Fundamentals: Part 5 – Dielectric Properties](https://blog.knowlescapacitors.com/blog/capacitor-fundamentals-part-5-dielectric-properties) Posted by [Simon Mao](https://blog.knowlescapacitors.com/blog/author/simon-mao) on May 1, 2023 9:00:00 AM - [Tweet](https://twitter.com/share) [![5](https://blog.knowlescapacitors.com/hubfs/5.png)](https://blog.knowlescapacitors.com/blog/capacitor-fundamentals-part-5-dielectric-properties) Welcome to the [Capacitor Fundamentals Series](https://info.knowlescapacitors.com/knowles-precision-devices-capacitor-basics), where we teach you about the ins and outs of chips capacitors – their properties, product classifications, test standards, and use cases – in order to help you make informed decisions about the right capacitors for your specific applications.

Those electrons then collide with the anode, which is a metal target usually made of tungsten. This process requires an input voltage typically ranging from 180 to 480 VAC with a power supply that transforms and steps up the voltage to extremely high voltage outputs ranging from 10kV and 120kV DC. A high-level diagram of the power supply required to power the X-ray tubes is shown in Figure 1.  [Read More](https://blog.knowlescapacitors.com/blog/selecting-capacitors-for-high-voltage-x-ray-power-supplies) 0 Comments [Click here to read/write comments](https://blog.knowlescapacitors.com/blog/selecting-capacitors-for-high-voltage-x-ray-power-supplies#comments-listing) Topics: [Capacitor](https://blog.knowlescapacitors.com/blog/tag/capacitor), [Medical](https://blog.knowlescapacitors.com/blog/tag/medical), [Filtering](https://blog.knowlescapacitors.com/blog/tag/filtering) ## [Supporting Medical Advancement at Knowles Precision Devices](https://blog.knowlescapacitors.com/blog/supp-orting-medical-advancement-at-knowles-precision-devices) Posted by [Rich Bestafka](https://blog.knowlescapacitors.com/blog/author/rich-bestafka) on Mar 25, 2023 8:00:00 AM - [Tweet](https://twitter.com/share) [![](https://blog.knowlescapacitors.com/hubfs/medical.jpeg)](https://blog.knowlescapacitors.com/blog/supp-orting-medical-advancement-at-knowles-precision-devices) At Knowles Precision Devices (KPD), we handle the specialty components that go in the systems that can’t quit.
