Abstract
Systems, circuits, and methods provide heat-sink-coupled conductive structures having eddy current mitigation structures, formed as S-notches, and integrated current sensors. An example conductive structure includes a high-current conductor structure having a main current path including an S-notch portion configured to mitigate eddy currents. The structure includes a low-current conductor structure connected to a first heat sink and having a main current path configured to conduct a second current. A differential current sensor is connected to the low-current conductor structure and configured to detect current flowing in the high-current conductor structure. A power module includes the conductive structure and a power converter that is configured to convert power between the first current in the high-current conductor structure and the second current in the low-current conductor structure. The conductive structures and power modules can be used for EV applications.
