Design and optimization of IGBT gate drivers for high insulation voltage up to 30kV
Résumé
In this article, a design methodology to
optimize IGBT gate drivers for high insulation voltage capability
(up to 30kV) is proposed. A Pot core ferrite with circular coils
transformer is used for high insulation capabilities. The
insulation voltage level is defined by the air gap length and the
dielectric material. The pulse width modulation (PWM) signal
transmission and power transmission functions of IGBT gate
driver are studied and optimized. For both functions, the
objective of the studies is to optimize the geometric elements of
transformer and the associated electrical components by the help
of a virtual prototyping tool. Therefore, the optimization results
are proposed under Pareto fronts: optimization objectives for a
set of the barrier insulation thickness. Finally, the experimental
verifications are shown to validate the proposed methodology.
