METHOD OF ELECTRIC ENERGY RECUPERATION IN IMPULSE AGGREGATES, AND DEVICE FOR METHOD IMPLEMENTATION Russian patent published in 2009 - IPC H03K3/53 

FIELD: electrics.

SUBSTANCE: invention concerns electric equipment and can be applied for impulse generation in active inductance loads. Method of electric power recuperation involves transformation of magnetic energy of electric current, obtained by transformation of charged capacitive storage energy into magnetic energy of electric current, into capacitive storage energy. During one cycle of impulse aggregate operation capacitive storage energy to magnetic energy of electric current and back is performed twice. At the first stage, capacitive storage energy is transformed into magnetic current energy in active inductance load with further energy recuperation to capacitive storage. At the second stage, capacitive storage energy is transformed into magnetic current energy in inductance coil with further energy recuperation to capacitive storage. Device includes capacitive storage connected to charging device and parallel to sequence of active inductance load and first key. Additionally device includes a circuit of sequential inductance coil and second key, circuit connected parallel to capacitive storage. First output of capacitive storage, first output of active inductance load and first output of inductance coil are interconnected and connected to positive output of charging device. Second output of active inductance load is connected to anode of first key, second output of inductance coil is connected to cathode of second key. Second output of capacitive storage, cathode of first key and anode of second key are interconnected and connected to negative output of charging device.

EFFECT: reduced heat loss during recharge, obtaining monopolar current impulses, eliminated necessity of charge current polarity commutation, simplified construction and key control scheme.
