    • A jump bar shunt structure 30 includes a base 32 constructed and arranged to be mounted to a substrate and to function as a current shunt; a pair of first legs 34 and 36 integral with the base and being constructed and arranged to be connected between terminals of at least two power devices such as MOSFETs; and a pair of second legs 50 and 52 integral with the base and being constructed and arranged to be connected to a printed circuit board so as to define a current sensing connection. The jump bar shunt structure is a single component that carries high current between two or more power devices and converts current into voltage that is used by the current measurement circuitry. The advantage of the jump bar shunt structure is that no high current (motor current) flows through a control PCB.
    • 跳杆分流结构30包括基座32,其被构造和布置成安装到基板并用作电流分路; 一对第一支脚34和36与该基座成一体并被构造和布置成连接在诸如MOSFET之类的至少两个功率器件的端子之间; 以及一对第二支脚50和52,其与基座一体地构成并被布置成连接到印刷电路板,以便限定电流感测连接。 跳杆分路结构是在两个或更多个功率器件之间承载高电流的单个组件,并将电流转换成由当前测量电路使用的电压。 跳杆分流结构的优点是没有高电流(电机电流)流过控制PCB。
