Helical magnetocumulative generator with compact transformer

Results of experiments with a helical MCG with internal helix diameter of 50 mm, supplied with a step-up transformer, are presented. The cylindrical transformer, located axially with the MCG and consisting of two solenoids, inserted into each other, is used. In comparison with the earlier published MCG, this one is more compact. The transformer allows powering of a high-impedance load of /spl sim/100 pH with power of /spl sim/1 kJ.

I. Introduction

Cascade systems, assembled from MCGs, in which each preceding generator is a power source for the next one are used to decrease weight and size of initial power source of magneto-cumulative generators (MCG) [1]–[3]. It is better to form this system based on helical MCGs, having high magnetic energy gain, combined by usual cylindrical step-up transformers [2]. These transformers are small and allow to power high-impedance loads.
