A Data-Driven Condition Monitoring Method for Capacitor in Modular Multilevel Converter (MMC)

Autor: Ou, Shuyu, Hassanifar, Mahyar, Votava, Martin, Langwasser, Marius, Liserre, Marco, Sangwongwanich, Ariya, Sahoo, Subham, Blaabjerg, Frede

The modular multilevel converter (MMC) is a topology that consists of a high number of capacitors, and degradation of capacitors can lead to converter malfunction, limiting the overall system lifetime. Condition monitoring methods can be applied to a

Semiconductor Devices Condition Monitoring Using Harmonics in Inverter Control Variables

Autor: Ou, Shuyu, Sangwongwanich, Ariya, Sahoo, Subham, Blaabjerg, Frede

The health status of power semiconductor devices in power converters is important but difficult to monitor. This paper analyzes the relationship between harmonics in inverter control variables and a health precursor (the on-state voltage Von of power

Realization of SVM Methods With Carrier-Based Dipolar PWM for Matrix Converters

Autor: Paiboon Kiatsookkanatorn, Somboon Sangwongwanich, Napat Watjanatepin

Publikováno v: IEEE Access, Vol 12, Pp 68531-68544 (2024)

Considering several space-vector modulation (SVM) methods, this study proposes SVM methods with carrier-based dipolar pulse width modulation (CBDPWM) for matrix converters. The switching patterns of well-known SVM methods are analyzed, and carrier-ba
