摘　　要：在对碳化硅基变换器中的桥臂串扰产生机理进行深入分析的基础上,提出一种新型有源箝位桥臂串扰抑制方法,并构成适用于碳化硅(Silicon carbide,SiC)基桥臂电路的串扰抑制驱动电路。给出其等效电路模态分析,讨论了关键参数的设计方法。设计制作了串扰抑制驱动电路模块板,并在1kW永磁同步电机(Permanent magnet synchronous motor,PMSM)驱动实验平台上进行了验证。实验结果表明,该方法能够有效抑制SiC基变换器中的桥臂串扰。The interaction between the upper and lower devices in a phase-leg configuration during switching is analyzed in detail, and a novel method to actively suppress crosstalk is proposed to fully utilize the potential of fast silicon carbide （SIC） devices. Moreover, this method is adopted in a driving circuit to suppress the crosstalk in SiC based phase-leg circuits. Through analysis of each operation mode of the proposed mitigation circuit, the design method of critical parameters is derived. Furthermore, to verify the validation of this method, a modular driving circuit is designed and testified in a 1 kW permanent magnet synchronous motor （PMSM） drive. Experimental results verify that the proposed method is feasible and reliable for crosstalk suppression in SiC based converters.
