Abstract
Wide bandgap devices are increasingly used in novel pulse modulator designs, especially for applications requiring nanosecond pulse widths and a high flat-top stability. For fast pulse generator designs, mainly two topologies have been investigated in recent years: Solid-state Marx generators and linear transformer drivers. In both concepts, the mounting space of the mechanical assembly – mainly determined by the required isolation distances – results in stray inductances and capacitances, which significantly influence the pulse shape of the generator. While various designs and measurements of the two topologies have been presented in literature, a detailed discussion and comparison of the parasitics is missing. This paper presents the calculation and comparison of the parasitics based on analytic equations and 3D FEM simulations. The obtained values are then related to equivalent circuits, which are used for transient simulations of the pulse waveforms. Show more
