Capacitors are widely used in dc links of power electronic converters to balance power,
suppress voltage ripple, and store short-term energy. Condition monitoring (CM) of dc-link …

Capacitors are one of the most critical components in power electronic converters, yet they
are notoriously susceptible to failure. Avoiding unforeseen outages caused by capacitor …

This letter proposes a novel health indicator for aluminum electrolytic capacitors (AECs)
based on strain sensing in a nonintrusive manner. The indicator leverages the mechanism …

Because of their temperature sensitivity, investigation of thermal effects on electrolytic
aluminum capacitors is required using ageing tests. In general, a reliability assessment …

Detecting leakage from liquid aluminum electrolytic capacitors is not easy. Typically there is
very little evidence of leakage because the electrolyte is volatile and leaves behind only …

The aging detection of dc‐link capacitors has great significance in enhancing the reliability
of the power electronic converters in photovoltaic applications. This chapter summarizes the …
