Transformer coupling for transmitting direct current through a barrier

Patent ·
OSTI ID:7065673

A system is described for transmitting direct current across a mechanical and electrical barrier from an energy source on a first side of the barrier to a load on a second side of the barrier. The system consists of: transformer means comprising a primary core disposed on the first side of the barrier, a secondary core disposed in alignment with the primary core on the second side of the barrier, a primary winding on the primary core for applying oscillating current thereto, and a secondary winding on the secondary core for applying transmitted energy to the load; means for converting direct current from the direct current energy source into oscillating current for application to the primary winding; means for converting alternating current from the secondary winding to direct current; optical link means for optically coupling the oscillating circuit to the secondary winding for regulating voltage on the secondary winding; and mechanical magnetic coupling means selectively movable between a first position and a second position, energy being transmitted from the primary core to the secondary core only when the magnetic coupling means is in the first position.
