Looking Closer At DC Link Capacitors In Electric Vehicles

DC link capacitors play a crucial role in the power management systems of electric vehicles (EVs), acting as a buffer between varying power sources and loads. In EV applications, these capacitors help mitigate the effects of inductance in key components such as inverters, motor controllers, and battery systems. They serve as essential filters, protecting subsystems from voltage spikes, surges, and electromagnetic interference (EMI).

This article delves into the functions and importance of DC link capacitors within EVs, highlighting their use in onboard chargers (OBC) and inverters, and recommending the high-capacitance StackiCap 1812-4040 for optimal performance in these critical applications.
