HV switches with current depending on-time, Thyristor / SCR  


 

● Robust and inexpensive HV switch for discharge applications and for the generation of damped sinusoidal oscillations in connection with fast high voltage FDA free-wheeling diodes ● High peak current capability ● Extremely high di/dt without compromises in reliability and life expectancy due to a large number of single SCR’s with individual gate drive ● Very overload tolerant   ●  Easy firing by a simple TTL trigger pulse (2-5 V)  ● Very compact and light weight  ● Many cooling options  

  
 

Note: The model number contains coded information about voltage, current and turn-on behavior. The first digits stand for the voltage in kV, the last digit before the dash indicates the
turn-on behavior (0 = fixed on-time, 1 = variable on-time). The digits after the dash indicate the current  in Amperes x10. Special features are coded by the letters after a second dash.
Example HTS 60-100-SCR:  HTS = HV Thyristor Switch, 6 = 6 kV,  0 = current depending fixed on-time , 100 = 1000 Ampere, SCR = Silicone Controlled Rectifier (thyristor). The switch
models are sorted by the dimension of housing and by maximum operating voltage within the dimension category.

Note: Any other customized voltage between 1 and 150 kV (AC/DC) and any other customized peak current between 1 and 100 kA is possible at moderate lead times (normaly 4-8 weeks). We do not charge extra costs for customized switches, if they can be realized on an existing platform. Please consult Behlke. We recommend direct liquid cooling (option DLC) or ceramic cooling fins (option CF-CER) or water cooling (option ILC) for the cooling at operating voltages above approx. 40 kV. Due to the strong electromagnetic fields, which can be caused by the high di / dt capabilty of the switches,  a separate control unit  (option SEP-C)  is recommended in all cases of unfavorable load circle wiring with large induction
loop areas. This applies especially for very large switching modules and if the di/dt is > 5 kA / µs.  For applications with small and medium switching modules we recommend printed circuit boards (eventually in multilayer technique) to minimize the stray inductance and to keep the areas of induction loops small.  A design with printed circuit boards ensures also
a reproducible EMC behavior of the whole electronic system.  Please ensure in any case,   that the load circle is in proper distance to the control circle to avoid magnetic feed-back effects, otherwise the internal safety electronics will detect a fault condition and the switch will be locked for 2 sec. after every shot. Most switches indicate this by a red LED.
