Capacitor Discharge
This is because the capacitor is discharging, meaning that the electrons are flowing in the opposite direction to the direction they were flowing while the capacitor was charging. Once the capacitor is fully discharged, the current will remain at zero until the switch is moved to position 1, which will cause the capacitor to start charging again.

When the load current increases rapidly, causing the load voltage to undershoot, S 1 switches from the ground (state 1) to the auxiliary source (state 2). The switched capacitor C 1 releases charge to the load to suppress the load voltage undershoot, and the direction of I 1 is from point B to point A. After C 1 has released the charge for a while, the real-time load …
