Abstract
An example printed circuit board (PCB) with integrated current sense includes a direct current (DC) bus including a first DC trace and a second DC trace. The PCB with integrated current sense further includes a planar Rogowski coil positioned between the first DC trace and the second DC trace and electrically separated from the first DC trace and the second DC trace. The planar Rogowski coil can extend beyond an edge-to-edge distance between a first side edge and a second side edge of the first DC trace in a first direction. The planar Rogowski coil can further extend beyond an edge-to-edge distance between a first edge and a second edge of the second DC trace in the first direction.
