B8: Capacitors, Dielectrics, and Energy in Capacitors
Moving charge from one initially-neutral capacitor plate to the other is called charging the capacitor. When you charge a capacitor, you are storing energy in that capacitor. Providing a conducting path for the charge to go back to the plate it came from is called discharging the capacitor. If you discharge the capacitor through an electric ...

Star and Delta Connection of Capacitors
Another disadvantage of this connection is that when capacitor on one phase fails, neutral point is shifted. The voltage across the unfaulted (healthy phases) will rise to full phase-phase potential. Current through the unfaulted capacitors reaches 1.732pu and the maximum current on the faulted phase will be 3pu. Such increase in voltage and ...

Lifetime Extension of DC-Link Capacitors in Three-Level Inverters Based on the Neutral …
This paper proposes the lifetime extension of DC-link capacitors in three-level inverters based on the neutral-point (NP) current. High-capacity inverters require large-size capacitors to maintain robust DC-link voltage. The proposed method suppresses the ripple current of the DC-link capacitors by replacing the switching states, which are …
