Calculate capacitors for supply voltage to half bridge

hi all would anyone provide me with the equation I should be using to calculate the capacitor values for C1 and C2 in the diagram attached they’re for the voltage supplies for this half bridge. I believe this will also include the switching frequency I have seen several sources with suggestions of values but no calculations to give a rough value. Would really appreciate a hand in this.

Kind Regards

Capacitors are calculated on the basis of permissible voltage drop, current value and pulse duration
C*deltaV=Tpw*I
for example: C=20us*10A/1V=200uF
