inverter output energy storage capacitor
DC link, energy storage, and pulse power capacitors
A DC link is typically connected to a rectifier (or other DC source such as a battery) and an inverter. 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.
