Capacitors on a DC intermediate circuit serve as buffers for power spikes in motor or generator actioned drive unit operation. They cushion system perturbations, i.e. line-conducted EMC, and as a snubber they function as filter components to protect the switching transistors from voltage peaks and high dU/dt (voltage gradient).
DC link capacitors are commonly used in power converters as an intermediary buffer between an input source to an output load that have different instantaneous power, voltages, and frequencies. In electric vehicle (EV) applications, DC link capacitors help offset the effects of inductance in inverters, motor controllers, and battery systems
