Fault Diagnosis of DC Link Electrolytic Capacitors in Inverter
The Transactions of the Korean Institute of Power Electronics, 2013 Electrolytic capacitors used for smoothing DC link voltage is one of the major root causes of fault in power electronic system. The aging of aluminum electrolytic capacitors is expressed by the increase of their equivalent series resistance (ESR) and the reduction of their capacitance.

An Evaluation Circuit for DC-Link Capacitors used in a Single-Phase PWM Inverter [PDF]
High-power conversion systems are based not only on three-phase inverters but also on single-phase inverters because modular multilevel cascade converters (MMCC) consist of half- or full-bridge single-phase converters.

Advanced Materials Interfaces, EarlyView.Macropore‐infused nanocomposite emulsion thermosets (MINETs) offer tunable multifunctionality due to their incorporation of structural resin, functional nanoparticles, and working fluid stabilized by surfactant. Here we show that if ionic liquid working fluids are introduced, structural capacitive (conductive particles) or separator (insulating ...
