A Step-Down Series-Parallel Dual-Resonant Switched-Capacitor …
Abstract: In this article, a step-down series-parallel dual resonant switched-capacitor converter (SP-DRSCC) is proposed to address issues of traditional SCC, such as high transient current spikes, inherent capacitor charge-sharing losses, hard-switched operation, and so on. The dual-resonant-core (DRC) is added to the traditional SP …
Current source and switched capacitors in parallel
A capacitor is characterized by its capacitance. The capacitance is measured in Farads (F) and defines the ratio between the amount of charge needed to increase one volt at the terminals of the capacitor. [ C= frac{Q}{V} ] Therefore, a capacitor with 1 F will need 1 Coulomb (1 C) of charge to set 1 V across its terminals.

Capacitors connected in parallel with a switch attached
To say Capacitor C1 reaches "equilibrium" simply means the voltage across the capacitor has stopped changing (i.e. the capacitor has stopped being charged by the battery) so that its voltage is now equal to (in equilibrium with) the battery voltage. At that point current will no longer flow to the capacitor. Hope this helps.
