The storage capacity in dynamic operation and for regenerative braking is
calculated as follows:
Formula: w = ½ S C S (V
Assumptions for the example:
Capacitance of the capacitor battery
Rated DC link voltage
Maximum DC link voltage
–3
––> w = ½ S 4.1 S 10 F S ((695 V)
In addition, 252 Ws for each C = 4.1 mF module can be stored for this voltage
range.
