Latest Patents

One of his latest patents is a vacuum switching assembly designed for switching AC or DC current. This assembly includes a vacuum switch with first and second electrodes located in a vacuum-tight enclosure. The enclosure contains a gas or gas mixture, and the electrodes are separated by a gap. Each electrode can connect to an electrical circuit carrying AC or DC voltage. The assembly features a pressure controller that manages the internal pressure of the enclosure, allowing for the selective switching between two vacuum levels. This innovation enables the formation and maintenance of a glow discharge to turn on the vacuum switch and inhibits it to turn off the switch.

Another significant patent is for a contact for a medium-voltage vacuum circuit-breaker with improved arc extinction. This vacuum circuit-breaker includes a contact body with two windings that are electrically connected in parallel. The design enhances the axial magnetic field and distributes it uniformly over the contact surface, improving arc extinction for high short-circuit currents, typically greater than 63 kA.
