High voltage transformer energy storage with variable coupling coefficient for pulse power generator

One of problems of nanosecond pulse power generators with transformer storage energy is energy output to load. At the moment of energy output voltage on primary winding will be in N-times above then on secondary one, where N - the relation of coils between primary and secondary winding. At usage as a breaker of combination of vacuum interrupter and plasma opening switch this question becomes the most actual since it is connected with efficiency of the generator project. In paper [1] it is offered for efficiency energy output from transformer store (TS) to load to change coupling coefficient. Now there are two ways of change of this value. The first is mechanical and the second, in transformers with a core, by core transfer to the saturated condition [2, 3]. In the project of tie pulse generator it is offered to reach necessary effect by electromagnetic shielding of a primarily winding, but only for the time energy output to a load. The estimation their efficiency is given at energy output to load with reference to the project of the pulse generator.
