DEVICE FOR CHARGING AN ACCUMULATING CAPACITOR Russian patent published in 2006 - IPC H02J7/10 

FIELD: pulse engineering, in particular, capacitive accumulators of electric energy; possible utilization for realization of methods of so-called "slow" charging during several periods of feeding voltage, for charging capacitive accumulators of electric energy, generators of powerful pulses.

SUBSTANCE: current-limiting batching elements are made in form of inductance coils, bridge transformer is made in form of autonomous voltage inverter based on lockable keys, to outputs of three-phased power source, inputs of three-phased network voltage indicator are connected, outputs of which are connected to some inputs of control block, inputs of three-phased bridge transformer are additionally connected to inputs of phase current indicators, outputs of which are connected to other inputs of control block, to output of three-phased bridge transformer voltage indicator of capacitive accumulator is connected, output of which is connected to other input of control block, to another input of control block, output of block for setting voltage value of accumulator is connected, and to yet another input of control block, output of block for setting speed of accumulator charging is connected. Principles utilized for building control system make it possible to realize in broad spectrum the smooth adjustment of charging speed of capacitive accumulator, while current of practically sinusoidal shape is consumed from the network, and utilization of inductors instead of current-limiting batching capacitors increases reliability of device.

EFFECT: increased charging speed of capacitive accumulator up to voltage, greatly exceeding amplitude of linear voltage of the network.
