IEEE Transactions on Plasma Science. ISSN 0093-3813. Vol. 45, N.º 12 (2017), pp. 3265-32700093-38131939-9375http://hdl.handle.net/10400.21/9726This paper describes a solid-state asymmetric bridge resonant topology to increase the energy efficiency of switching pulse modulators. The solid-state resonant topology will replace an existing pulse transformer and thyratron-based resonant modulator to supply the 60-kV target potential for the ion acceleration of the On-Line Isotope Mass Separator ISOLDE accelerator. An experimental prototype is tested in order to validate the proposed concept, including a low auxiliary voltage power supply to compensate the losses in the circuit. The design of the circuit components and the experimental results for a 6-kV prototype are presented and discussed, as well as the design procedure and parameters for the 60-kV modulator, including a high-voltage gapped coil core.engAccelerator power supplyEnergy efficiencyEnergy recoveryHigh-voltage pulse circuitResonant converterFonte de alimentação do aceleradorEficiência energéticaRecuperação de energiajournal article10.1109/TPS.2017.2765350
