Can capacitors be added to high voltage inverters

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.

Are electrolytic capacitors good for hard switched inverter bus link capacitors?

Electrolytic capacitors have been the workhorse technology for hard switched inverter bus link capacitors for many years. Electrolytic capacitor technology has also remained virtually unchanged over the years. Up till now, the greatest benefit in using electrolytic capacitors for bus link capacitors in inverters has been their cost.

Are film capacitors better than electrolytic capacitors?

Many high performance inverters such as electric vehicles, aircraft, and alternative energy to name a few are now turning to film capacitors because they do not have the limitations of electrolytic capacitors. Moreover, modern film capacitors not only perform better but can be a cost effective technology as well if applied correctly.

What happens if a bus link capacitor is too high?

Having an excessive amount of bus link capacitance also presents some safety concerns. Once the inverter is powered down, a large amount of energy is stored in the bus link capacitor and this energy can be depending on the voltage, lethal if touched by an unsuspecting repair person.
