Zusammenfassung:Systems and methods of detecting non-uniform aging and degradation of power assembly units are disclosed. The system may include a first power assembly unit and a second power assembly unit adjacent to the first power assembly unit. Each of the first and second power assembly units has a coupling capacitor and a number of electrical components. The system may further include a current sensor in between the coupling capacitors of the first and second power assembly units to detect a current spike in the coupling capacitors and the electrical components.
