Capacitor back-to-back structure
Back-to-back switching (BTBS), i.e., switching of a second capacitor bank on the same bus in the presence of an already energized bank; (3) Outrush current, i.e., discharging of an SCB into a short-circuit fault in the upstream system. It should be noted that outrush current amplitude can reach 300 times the rated current. (4)

DC-Link Design Tips
The DC-Link capacitor must regulate voltage and absorb ripples in the current, as well. A ripple wiggles the level of the voltage that appears across the DC-Link capacitor while the switching current''s ripple travels through the capacitor (V=IR). One must also consider inverter switching frequencies that the DC-Link capacitor must tolerate.
