DC link, energy storage, and pulse power capacitors
A DC link capacitor is used as a load-balancing energy storage device. This capacitor is connected in parallel between the positive and the negative rails and helps prevent the transients on the load side from going back to the input side. It also serves to smooth the pulses in the rectified DC input. The selection of the correct DC link ...
