                     High Voltage Power Pulse Generators

     We can offer You pulse current generators for electrohydroimpulse technotogies. Such devices  can also be applied as the pulse sources of energy in other  electrophysical installations.
     The construction of powerful pulse systems is based on the principle of slow accumulation of energy, for example, in the electric field of a capacitor and its rapid return into the load. Pulse current generators (PCG) embody this principle. PCG structure is shown below.
     PCG consist of: charge device, capacitance module, high voltage discharger, capacitance charge blocking system, defense and  control systems. Capacitance module (C), high voltage discharger (D) and the load comprise discharge loop together. Electrical PCGs scheme is shown below.
     Capacitive energy storage is a common element of the charge and discharge PCGs circuits. Charging processes do not affect on discharge processes. They only determine its initial conditions. Charging processes are regulated by a microprocessor control system, which provides smooth regulation of the charging current in a wide range.
                                                                                             Trakonta ltd
                                          Pulse current generators
      When the PCG is turned on, charge device begin to accumulate the energy in to capacitance. Upon reaching the installed voltage across the capacitance, the spark gap start to trigger. A circuit is closed. The energy stored in capacitance flow to the load through the power wires.

     Physical description of PCGs
Electrical specifications of PCGs.

Rated Output Voltage
The output voltage is continuously adjustable by spark gap
from 0 to 100 % (full scale). PSGs have built up electronic module, which allow to realize fine adjustment of output voltage impulse in the range from 0 to 70 kV.

Output current
The output current depend on load parameters. Digit current pulse amplitude can be up to 1 MА.

Repetition rate of discharge impulses
Repetition rate of discharge impulses regulation: ± 0.05 % of full current (for 0 – 100 % load)

Stored energy
The stored energy can be discretely regulated by adding capacitors in parallel or series.

Against short circuit & HV arc to ground
Shutdown on over temperature & open interlock

Operating temperature: from 0 to 40°C

Mains Voltage: 380-400 VAC ±10% 45 – 65 Hz 3 Phases + Earth

Inrush current: limited to full power operating current

    Discharger is cooling by air. Reversibility and floating outputs. (Polarity can be positive, negative, floating or reversible). The PCG can have a modular structure, and consist of separate independent cells and a united control unit, assembled in a post.

Customer remote adaptation.

Any special requests can be considered.

     The PCGs is recommended to apply in the following fields: electrohydraulic installations, metal dispersing plants, power acoustic systems, pulse welding, medical facilities, electrolytic heating, laser pumping systems, plasmotrones, pressing machines, etc.
      The pulse current generator is a source of high-voltage current pulses. PCG is designed to increase the mains voltage, rectify it, charge high-voltage pulse capacitors, switch the energy stored in the electric field of the capacitors.
      GIT is a complex technical system in which a number of physical processes take place. This processes are different both in the physical quantities characterizing them and in the rate of flow. These are primarily charging processes, which can include several types of energy conversion, processes in the switch, power loop wires and load.
