High-efficiency pulsed charging of capacitors by exploding wires

Pulsed charging of a capacitor from an LC circuit by means of exploding wires (EW) has been investigated experimentally using a method of physical simulation. The efficiency of energy transfer is shown to be a maximum under the matched condition, when the specific action of the electrically exploded wire is equivalent to the potential action of the circuit. By the time of switching-on the capacitor, the specific energy introduced into the wire must be equal to the sublimation energy. Under this and other specifying conditions, the energy stored in the circuit inductance is 0.56W0 at the maximum current. Simultaneous with variation of the circuit and load parameters, the EW parameters were varied with conservation of the similitude. As a result the overvoltages K= 4÷6.7 have been achieved with the transferred energy 0.5W0.
