传统的分立母排寄生电感量过大,在功率开关管关断瞬间产生的瞬态电压与直流回路电压叠加,对功率开关管构成威胁。分布电感量越大,负载电流越大,功率开关管的电流下降时间越短(di/dt),危害越严重,且该危害不会因为功率开关器的选择而消失。The parasitic inductance of the traditional discrete busbar is too large, and the transient voltage generated at the moment the power switch is turned off is superimposed on the DC link voltage, posing a threat to the power switch.
