Contact UsSelecting and Applying DC Link Bus Capacitors for Inverter …
We may infer from Figure 2 that the DC link capacitor''s AC ripple current Icap arises from two main contributors: (1) the incoming current from the energy source and (2) the current drawn by the inverter. Capacitors cannot pass DC current; thus, DC current only flows from the source to the inverter, bypassing the capacitor.
