Optimised design of a transformer and an electronic circuit for IGBT drivers signal impulse transmission function based on a virtual prototyping tool
Résumé
In this study, a signal impulse transmission function is investigated which provides high insulation voltage capabilities for IGBT drivers devices. This electrical insulation is achieved with a printed circuit board (PCB) and classical copper windings. Two ferrite cores are added to improve the magnetic coupling effect and thus decrease the impulse current maximum value in the primary side. The electronic circuit involves a series resonant topology in the primary side and a parallel one in the secondary side. The classical electronic components lead potentially to cost-effective solutions. However, so as to optimise the proposed system, a design methodology based on virtual prototyping tools is carried out. The simulation results presented on a Pareto front are analysed with the help of propagation delay and average power consumption. Moreover, measurement results with a 1.6 mm PCB are compared with simulation ones. Finally, the proposed solution and the methodology design are clearly accurate and suitable for power electronic designers and especially for IGBT driver devices designers.
