Consider battery bank is connected to grid through bidirectional dc dc converter and three phase inverter. The energy storage capacitor is connected in between dc dc converter and three phase inverter .How can I calculate the value of capacitor?
Hello,
Grid-tied bidirectional DC-DC Converter technology is combined with Buck Converter and Boost Converter in different bridge configurations based on the switching mode.
Two important parameters that needed to optimization are Inductance and Capacitance.
Regarding the capacitance, its large capacitance value can cause turn-off loss reduction and turn-on loss increase.
I would like to share the following link:

Sagar Modi:
The value about capacitor is determine for the demand of inductive reactive.
You can to choose for de average or through the efficacious values maximums that was registered in the period of the measurements (realized with an measuring instrument; network analyzer, digital-record-meter, etc.).
After should calculate the capacity fore the total cKvar and after obtained, to certain value of voltage, the capacitance in MicroFarad.
