A typical configuration of a DC solid-state transformer is formed by connecting standardized power conversion cells in an input-series output-parallel (ISOP) arrangement to achieve DC transformation from medium voltage to low voltage. To provide redundancy for the power conversion cells, a thyristor bypass circuit is typically required. While DC solid-state transformers generally employ SiC MOSFET devices, the high dv/dt characteristic of SiC MOSFETs can readily false triggering in the thyristor bypass circuit. The issue of false triggering in thyristor bypass circuits is focused on, and a co-design methodology involving the thyristor snubber circuit and the gate-parallel resistor is explored. The proposed approach aims to enhance the operational reliability of the thyristor bypass circuit in high dv/dt environments, and experimental validation is provided.

直流固态变压器的1种典型结构由标准功率变换单元输入串联输出并联组合构成,以实现中压到低压的直流变换。为实现功率变换单元的冗余,需要配备晶闸管旁路电路,直流固态变压器一般采用SiC MOSFET器件,然而SiC MOSFET器件的高dv/dt易使晶闸管旁路电路出现误导通。围绕晶闸管旁路电路误导通问题,探讨晶闸管缓冲电路与晶闸管门极并联电阻的协同设计方法,以适应高dv/dt环境,提升晶闸管旁路电路运行的可靠性,并进行了实验验证。

直流固态变压器的1种典型结构由标准功率变换单元输入串联输出并联组合构成,以实现中压到低压的直流变换。为实现功率变换单元的冗余,需要配备晶闸管旁路电路,直流固态变压器一般采用SiC MOSFET器件,然而SiC MOSFET器件的高dv/dt易使晶闸管旁路电路出现误导通。围绕晶闸管旁路电路误导通问题,探讨晶闸管缓冲电路与晶闸管门极并联电阻的协同设计方法,以适应高dv/dt环境,提升晶闸管旁路电路运行的可靠性,并进行了实验验证。

A typical configuration of a DC solid-state transformer is formed by connecting standardized power conversion cells in an input-series output-parallel (ISOP) arrangement to achieve DC transformation from medium voltage to low voltage. To provide redundancy for the power conversion cells, a thyristor bypass circuit is typically required. While DC solid-state transformers generally employ SiC MOSFET devices, the high dv/dt characteristic of SiC MOSFETs can readily false triggering in the thyristor bypass circuit. The issue of false triggering in thyristor bypass circuits is focused on, and a co-design methodology involving the thyristor snubber circuit and the gate-parallel resistor is explored. The proposed approach aims to enhance the operational reliability of the thyristor bypass circuit in high dv/dt environments, and experimental validation is provided.
