| Abstract |
Active droop compensation systems, so called active bouncers, for klystron modulators based onmonolithic pulse transformers perform the regulation of the output pulse voltage while simultaneouslywithstand all the primary current of the modulator. This imposes the utilization of high powersemiconductors which can produce high switching losses and degrade the overall system efficiency. Inorder to overcome this issue, this paper proposes a new active bouncer topology based on the parallelconnection of two different power converters: the first one is in charge of handling the majority of theprimary current at high efficiency, and the second one is used to fine tune the bouncer voltage via ahigh bandwidth converter rated at a fraction of the first parallel connected converter. Detailedcomparison between a classical active bouncer and two variants of the proposed topology arepresented and based on numerical simulations. |
