How much capacitor should be used with a 2000W high frequency inverter

How to sizing capacitors for inverter bus link applications?

The first step in sizing capacitors for inverter bus link applications should be to understand how much bus link capacitance is required for a given inverter design. The biggest design limitation for electrolytic capacitors in inverter applications has been the amount of ripple current that the electrolytic capacitor can sustain.

Are film capacitors a good choice for inverter power bridges?

Moreover, modern film capacitors not only perform better but can be a cost effective technology as well if applied correctly. inductance in an inverter power bridge leads to inefficiencies due to the voltage spikes they produce when the power devices are switched on and off at a high rate of dI/dt.

How do I choose a capacitor for a high-frequency system?

In addition to the actual capacitance value, there is a short list of specifications to look at when selecting capacitors for high-frequency systems. Case size: Smaller case sizes tend to have higher self-resonance, and they can access smaller capacitance values (see below).

Do film capacitors cost more per UF than electrolytic capacitors?

Film capacitors do cost more per uF than electrolytic capacitors. It will be shown in this paper that the amount of capacitance needed for an inverter bus link capacitor design is much less for a film capacitor than an electrolytic capacitor since the film capacitor is not limited by ripple current rating like the electrolytic capacitor is.
