Abstract
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.
