In steady state, the average charge across capacitor C1 in a period should be zero. The relations are available:

This relation is available for all capacitor’s current in switch-on and switch-off periods. The input current iin is equal to (iL1 + iC1) during switch-on and zero during switch-off. Capacitor current iC1 is equal to iL1 during switch-off.
