Switch-mode power supplies, inverters, and converters all generate AC ripple that flows into and out of capacitors. While a ripple current rating may seem secondary to a capacitance or voltage rating, in real-world designs, it is often a limiting factor for long-term reliability. This is because ripple current generates internal heat, and excessive heat is a primary driver of capacitor failure. To prevent premature failure, it’s critical for engineers selecting power electronics capacitors to truly understand ripple current ratings.

This is because when silicon and carbon are combined, the resulting material, SiC, has excellent mechanical, chemical, and thermal properties. Therefore, SiC-based converters can handle voltages up to 10 times greater than converters using just Si while also offering lower losses. These characteristics make these converters an excellent option for applications such as power electronics, industrial devices, and electric vehicle (EV) charging stations. In this post, we dive into the advantages of using snubber circuits to protect SiC-based converters and discuss how to further increase these efficiencies by focusing on capacitor selection.

Together, these pressures are creating an urgent need for more resilient and responsive power distribution architectures. For many instances, a key solution that offers better resiliency, efficiency, and flexibility is the implementation of microgrids, or localized energy systems capable of operating independently of or alongside the main grid. Microgrids bring together a variety of distributed energy resources (DERs) such as [solar](https://blog.knowlescapacitors.com/blog/common-capacitors-in-solar-power-conversion-systems), [wind](https://blog.knowlescapacitors.com/blog/trends-in-wind-power-generation), [battery storage](https://blog.knowlescapacitors.com/blog/trends-in-battery-energy-storage-systems), and even conventional generators.
