ELECTROMAGNETIC UNIT FOR THROWING OF DIELECTRIC MACRO BODIES Russian patent published in 2014 - IPC H05H15/00 F41B6/00 

FIELD: electricity.

SUBSTANCE: electromagnetic unit for throwing of dielectric macro bodies contains a power supply unit, a unit of passive imposed load (UPIL) and N of propellant-recuperative modules (PRM), at that the first and second outputs of the power supply unit are connected to the first and second UPIL inputs respectively and also to the first and second inputs of each PRM. The first output of each PEM is connected to the third UPIL input, the second output of the n^th PRM is connected to the third input of (n+1)^th PRM, where n=1, 2, …, (N-1), N≥2, and the second output of N^th PRM is connected to the third input of the first PRM. Each PRM includes a rail electromagnetic accelerator (REA) which is equipped auxiliary with a recuperative inductive transducer with the main and auxiliary windings and a projectile position sensor; two recuperators, two semiconductor switches, two saturating chokes, a storage capacitor, a diode and three keys. The first output of the first saturating choke is the first input of PRM. The second output of the first saturating choke is connected to the first REA electrode, while its second electrode is connected to the positive output of the first semiconductor key and positive output of the diode which negative output is the second input of PRM and it is connected to the second output of the storage capacitor, the first outputs of windings of the recuperative inductive transducer and the second outputs of the both recuperators. The negative output of the first semiconductor switch is the third output of PRM and it is connected to the first output of the storage capacitor and the first output of the first key, which second output is the first output of PRM. The first output of the main winding is connected to the first output of the second saturating choke and the first output of the second key, which second output is connected to the first output of the first recuperator. The second output of the second saturating choke is connected to the negative output of the second semiconductor key, which positive output is the second output of PRM while the second output of the auxiliary winding is connected through the third key to the first output of the second recuperator.

EFFECT: improving usage efficiency of electric energy stored at the inductive storage of the power supply unit.
