Abstract, aluminum electrolytic and DC film capacitors are widely used in all types of inverter power systems, from variable-speed drives to welders, UPS systems and inverters for renewable energy.
For three-phase inverters at any DC bus voltage, for films and electrolytics, respectively, a rule of thumb is that about 5 and 50 millicoulombs of capacitor nameplate CV rating will be required per amp of ripple current.
One of the main application classes of aluminum elec-trolytic capacitors is input capacitors for power invert-ers. The aluminum electrolytic capacitor provides a unique value in high energy storage and low device impedance. How you go about selecting the right ca-pacitor or capacitors, however, is not a trivial matter.
Because, the ripple current ends up being the driving requirement, most modern inverters use film capacitors. Compared to electrolytics, film caps have high ripple current rating due to their low ESR and ESL.
