此外，损害可能发生的预充电电路如果试图这样因为充电电阻将保持电路的直流总线，和充电没有完成。

Additionally, damage may occur to the precharge circuitry if this is attempted because the precharge resistor will remain in circuit with the DC bus, and precharge never completes.

这是参考输出。它提供了电容CT充电电流通过电阻RT。

Vref:This is the reference output. It provides charging current for capacitor CT through resistor RT.
