Design Of High Voltage Pulse Generator With Back To Back Multilevel Boost Buck Converters Using Sic-Mosfet Switches

摘要

This paper presents a high voltage pulse generator using SiC-Mosfets switches. This generator has to provide a pulse burst for high frequency applications (>100KHZ) with an amplitude greater than or equal to 1KV. This design is developed by two back to back converters. First part of this prototype is based on a threelevel boost converter and second part is based on a three-level buck converter. This protype can be used in different industrial applications such as: medical treatment or physical and chemical fields. In this paper, first, we present the structure of this design then we validate this a proposed topology with simulation and experimental results.
