Abstract
Capacitors (10,20,40,50,70,80) having a fluid dielectric material that is transported or undergoes a phase change are disclosed. The dielectric medium change results in a change in the total dielectric constant of the material between the electrodes (12, 14, 72, 74, 81, 82), thus changing the capacitance of the capacitors. Transporting or phase changing the dielectric fluids into and out of a the electric field of the capacitor, changes the effective dielectric constant and the capacitance of the capacitor.
Claims17
A capacitor comprising:
- a first electrode;
- a second electrode;
- a dielectric material;
- and means for changing the dielectric constant of the dielectric material via a phase change of the dielectric material from liquid to solid, liquid to gas, or solid to gas, or vary physical properties of a supercritical fluid.
