INNOVATIVE APPROACH OF SOLVING THE ISSUE WITH AN ARC-LESS TURN OFF, OF A MAGNETIC FIELD
The article describes the construction of a device that turns off a magnetic field, in particular, creating an instrument that arc-less commutate the electric circuit. Currently there are two issues when creating an optimal device which turns off the magnetic field. First, an arc-less turn off, of an inductive load has to be ensured. Second, the diffusion of magnetic energy in form of heat has to be eliminated. In this context, the innovative approach can be considered as load’s return of magnetic energy to the power supply, when turned off. In other words, recuperation should take place. The article describes a setup developed by the authors regarding a device that turns off the magnetic field for circuits of small and middle capacities. One of patter’s advantages is thereby a full recuperation with negligible heat losses.
