Abstract:
To integrate multi-module pulse power supply and improve current waveforms,a three-dimensional finite element model and a Maxwell equation of the bus bar are established. An edge finite element method is used to resolve the magnetic density,and H of the boundary should be continuous. Continous resolves of the magnetic field are generated from divided units. The error result is analyzed,and the bigger error units are refined automatically. This paper continues to resolve the equation until the solution meets the error requirement. The self induction and the mutual inductance of the bus bar are given by calculating the magnetic field energy. The simulation results are compared with the empirical formula. The results show that increasing the width of the conductor or decreasing the distance between conductors can effectively reduce the stray inductance of the bus bar. It is feasible to calculate the inductor using the finite element method.
