ZVS and Inrush Charging Current Suppression Design for Switched-Capacitor Multilevel Inverters
IEEE transactions on power electronics, 2023Switched-capacitor (SC) based multilevel inverter (MLI) technique has been developed rapidly in recent years. However, the majority SC-MLIs operate with hard-switching and suffer from the inrush charging current problem of capacitors.

Startup Control to Eliminate Inrush Current for Star-Connected Cascaded H-Bridge STATCOM
IEEE transactions on power electronics, 2022Soft startup is essential to the operation of the star-connected cascaded H-bridge (CHB) STATCOM. The conventional startup stage involves only uncontrolled rectifier process in which the dc voltages are charged by inserting startup resistors to limit the

This article presents the harmonic analysis of transformer inrush currents in offshore power systems. Offshore production facilities interconnected by subsea cables are becoming increasingly common, either as new projects or as extensions to existing facilities. Interconnection via a subsea cable introduces a significant shunt capacitance to the source

Sequence Current-Based Inrush Detection in High-Permeability Core Transformers
IEEE Transactions on Instrumentation and Measurement, 2023Modern transformers are designed with high-permeability core material to lower losses and noise levels. During energization, the transformer enters the ultrasaturation region and loses properties such as the dead angle and second harmonic content in ...

Inrush Current Mitigation for Grid-Forming Inverters in Islanded Microgrids
European Conference on Cognitive Ergonomics, 2022Virtual-inertia and droop control methods are commonly used for grid-forming inverters. While the virtual inertia is used to emulate the equation of motion/frequency, if the inverter output voltage is emulated as in synchronous generators, then the ...
