- 説明
The BIMT‑500‑9.0‑1‑E‑UHL4 pulse unit is a power semiconductor switch for pulsed current, designed to generate a single current pulse with an amplitude of up to 500 A at a switched voltage of 9 000 V (9 kV).
The unit is built on thyristors with air cooling and is used in pulsed electrophysical installations and capacitor discharge systems.
The operating mode is single‑pulse switching. The unit is not intended for continuous voltage or current conversion.
Its task is to pass a single current pulse through the load, stored in a capacitor bank or inductive energy storage. The pulse duration ranges from 100 to 1 000 microseconds, corresponding to the operating mode of pulsed electrophysical installations.
All power units manufactured by Proton‑Electrotex JSC can be additionally equipped on request: snubber circuits for protection against switching overvoltages, resistive dividers, current, voltage, and temperature sensors, and various types of drivers.
Power assemblies are developed to meet individual customer requirements — simply fill out the dedicated questionnaire to specify your parameters.
- 用途
The pulse unit is designed for use in pulsed power systems — installations where energy is stored in a capacitor bank or inductive energy storage and then released into the load as a short, high‑power current pulse.
Operating principle in a pulsed system. During the interval between pulses, the capacitor bank is charged from a DC source to the required level (up to 9 kV). The thyristor switch of the unit is closed — the load is disconnected from the energy source.
Upon a command from the control system, a control pulse is applied to the thyristor stack — all thyristors turn on practically simultaneously, and the capacitor bank discharges through the load. The current pulse waveform is determined by the parameters of the discharge circuit (capacitor capacitance, circuit inductance, and load resistance) and can be close to a half‑sine with a duration of 100 to 1 000 microseconds.
Difference from the higher‑rated model BIMT‑5200. At the same voltage of 9 kV, the BIMT‑500 unit switches a current pulse of 500 A, while the BIMT‑5200 switches 5 200 A — more than ten times greater. The BIMT‑5200 is equipped with specially designed pulse thyristors with high di/dt withstand capability and a control pulse with a high rate of rise for synchronous turn‑on. The BIMT‑500 is intended for lower‑current applications where standard thyristors in a series assembly are sufficient.
Typical applications:
- Capacitor banks of pulsed installations — discharge of a pre‑charged bank through the load to produce a current pulse of specified amplitude and waveform; the unit functions as a semiconductor spark gap;
- Energy storage and switching systems — discharge switches for capacitive energy storage with pulsed currents up to 500 A at voltages up to 9 kV;
- Modulators with capacitive energy storage — generation of high‑voltage pulses for powering vacuum electronic devices (klystrons, magnetrons); the thyristor switch replaces gas‑discharge switches and hydrogen thyratrons, providing longer service life and absence of degradation;
- Power supply to electromagnets and coils — pulsed power supply to windings with inductive load characteristics;
- Magnetic pulse metal‑working installations — generation of current pulses to create a pulsed magnetic field;
- Pulsed test benches — reproduction of impulse effects (switching overvoltages) for testing the insulation of high‑voltage equipment; impulse voltage and current generators.
Pulsed thyristor units of this class are used where switching of current pulses with amplitudes up to 500 A at a high voltage of 9 kV is required, with a service life of hundreds of thousands of switching cycles and no mechanical wear.
