Studying Autonomous Magneto-Cumulative Energy Source

Helical magneto-cumulative generator (MCG) powered from explosive piezogenerator (EPG) is the most compact device among modern sources having output energy of 1-10 kJ. EPG matches well MCG on nature of their operation and design parameters; they are simple in use and do not require transforming and switching devices. This paper presents the results of the work on creating an autonomous small energy source based on EPG and MCG. The energy on the piezogenerator output reaches ~25 J at the expense of double-sided shock loading of the EPG piezoceramic unit. The energy is transmitted to the helical MCG with the initial inductance of ~1000 μH. Constructively, the energy source is made both in the form of a monoblock of ~2 dm³ volume and in the form of two separate units, connected with high-voltage cable.
