In the framework of the development of pulsed klystron modulators for particle accelerators, this paper presents a complete study of a novel hybrid topology of a bouncer circuit used to compensate the voltage droop of the main capacitor bank. This topology allows to merge the advantages of the open loop passive L-C resonant bouncer topology with an active linear bouncer one. The resulting performances are of great interest for highly repeatable modulators. The solution improves the pulse shape correction made by the passive bouncer alone, leads to a lower sensitivity to parameters deviation and causes a limited level of losses. This paper establishes the merits of such a topology through analytical and numerical studies.
