  • Demo: Characterizing the Behavior of a Capacitor

White Paper Overview 

The increasing use of WBG semiconductor materials such as gallium nitride (GaN) and silicon carbide (SiC) in power converters has allowed for highly power-dense supplies with low switching losses and a higher efficiency during operation. However, the benefits of these fast switching transistors used within power converters can be limited if the effects of parasitics appearing at high frequencies are not considered.

This white paper provides an introduction to parasitics & illustrates how parasitics can impact passive components like capacitors, inductors, and resistors. Learn more about the LCR meter and how it is an excellent tool for this characterization.
