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.
