Dynamic current mode power supply with a 3P 4Q PFC module and with energy recuperation ability to the mains for feeding superconducting paricle accelerator magnets

摘要

This paper presents a developed four quadrant, three phase, AC to DC converter for dynamic mode, current source power supplies with ability of energy recuperation from the load to the mains. The developed converter will be a part of universal and modular platform for current source power supplies, feeding superconducting magnets in particle accelerators. The main advantages of the developed 4Q module are the unity power factor at the input and the energy recuperation ability from the superconducting magnets to the mains. This paper presents some design aspects, performances and test results of the developed 4Q PFC converter and the developed, new power supply concept.
