4. Electrostatic generators
4.1 Operating principle
An electrostatic generator is based on the variation in electrical force between two capacitor plates moving relative to each other. There are two main operating cycles: constant charge or constant voltage.
For example, in a constant-load cycle, the capacitor is charged when its capacity is at its maximum, then isolated from its load and the polarizing source; the structure stores an initial energy. The mechanical movement imposed on the structure varies the value of this capacitance. As the armatures move apart, the voltage across them increases, since the load is constant (Q = CV ). Finally, the charges are removed from the structure below its minimum capacity. The electrical energy thus recovered...
