Series NTN from 6.5V to 350V / 35W to 100kW

The mains voltage is transformed to the appropriate level. On the secondary side of the transformer is a thyristor controlled rectifier stage (phase cutting circuit), the output of which is used to charge a capacitor bank. This capacitor bank is also connected to the final series regulating transistor output stage. By controlling the conduction angle of the thyristors after each zero-crossing of the sinusoidal voltage, the flow of energy is regulated in such a way as to have a defined voltage drop across the final series transistor stage (pre-regulation). The performance of the final series transistor stage defines the final stability of the output voltage (main regulation).

Serie NTS

Designed specifically for superconductivity applications, this superconductivity power supply family is series regulated via a set of parallel transistors which are driven from a pre-regulation stage which utilises phase controlled thyristors. In this manner, the power lost across the output transistors is kept to as minimum. Thus, the final control element always has a low power dissipation in energizing and static constant current mode. In de-energizing mode, the transistor stage is working as a current sink and the power is dissipated by means of either air or water cooling.

  • Double stabilization for superconducting coils
  • To charge and discharge high-inductive, superconducting coils
  • Quench detection feature
