How does opening and closing the switch store energy?

In electrical circuits, the act of opening and closing a switch facilitates the storage of energy in specific components. 1. When a switch is closed, current flows through the circuit, enabling inductors or capacitors to store energy, 2.While opening the switch interrupts the current flow, the previously stored energy can be released as needed, 3.

The energy harvested on the storage component is thus only 2.4% of the energy converted by the system (1 μ J/cycle), as the main part of the converted energy is lost on the parallel resistance of the transducer (low at high frequencies). Hence, harvested energy can be increased by using components that have small losses at high frequencies.
