Abstract
This paper analyzes the mechanism of the production about the surge voltage during IGBT switching off, for the problem of surge voltage in Cascade STATCOM. On this basis, the optimal design of the low stray inductance and simplified buffer circuit is proposed in the paper. Appropriate selection of components and application of laminated bus bar can reduce the stray inductance in circuit, which coupled with the simplified buffer circuit can effectively suppress the spike voltage and reduce the system loss under the premise of IGBT works in the area of safe operation. Besides, the design of driving circuit based on CONCEPTs 2SC0108T is given. Finally, the elementary experimental sample verified the validity and applicability of this design.关键词
