“…The reader is directed to ref. [1][2][3][4][5][6][7] to find some practical realizations of Marx generators with high-level characteristics. Several techniques were developed to improve the spark gap (SG) performances: placing the gap in an appropriate gas mixture at high pressure (up to 20 bars), inserting Marx modules in metallic housing to increase the stray capacitance or using a line-of-sight geometry to obtain a stable Marx erection due to ultra-violet photo-ionization.…”

“…However, it can be affected by factors such as the shape and distance, and for the laminated busbar, it is very complicated to accurately calculate the external inductance. Generally the approximate calculation, as shown in [24], can be realized by:…”

Laminated busbars with a low stray inductance are widely used in NPC three-level inverters, even though some of them have poor performances in heat equilibrium and overvoltage suppression. Therefore, a theoretical method is in need to establish an accurate mathematical model of laminated busbars and to calculate the impedance and stray inductance of each commutation loop to improve the heat equilibrium and overvoltage suppression performance. Firstly, an equivalent circuit of a NPC three-level inverter laminated busbar was built with an analysis of the commutation processes. Secondly, on the basis of a 3D (three dimensional) cubical thermal model and mirror circulation theory, a supersymmetric mirror circulation 3D cubical thermal model was built. Based on this, the laminated busbar was decomposed in 3D space to calculate the equivalent resistance and stray inductance in each commutation loop. Finally, the model and analysis results were put into a busbar design, simulation and experiments, whose results demonstrate the accuracy and feasibility of the proposed method.
