Webinar: Addressing MLCC Performance Issues in High-Voltage EV Applications

In recent years, multilayer ceramic capacitors (MLCCs) have emerged as an excellent capacitor option for the high-power electrical systems needed in electric vehicle (EVs) due to their small physical size, very low inductance, and ability to operate at higher temperatures. However, EV engineers are facing two big challenges with using MLCCs including DC bias that can cause capacitance loses of 80 to 90 percent of their quoted value and self-heating issues from AC ripple that leads to inefficiencies in circuits and increased cooling demands. 

To take advantage of all the benefits of MLCCs without causing inefficacies elsewhere, EV engineers need a way to manage these issues. In this webinar, we dive into these MLCC inefficiency issues and how they can be addressed by covering the following information:

• How capacitance changes with applied voltage
• The rules you need to follow to avoid overvoltage
• Performance characteristics of various dielectrics
• How new high-stability, low-loss materials can address these known performance issues
