A Simple Carrier-Based Modulation for the SVM of the Matrix Converter [PDF]
, 2013 Today, industry has not fully embraced the matrix converter solution. One important reason is its high control complexity. It is therefore relevant to propose a simpler but efficient modulation scheme, similar as three phase voltage source inverter ...

Impact of Digital Control Delay on Stability of Grid-Following Converters
2022 IEEE 13th International Symposium on Power Electronics for Distributed Generation Systems (PEDG), 2022 In a digital controlled system, the delay is inevitable. It will change the phase-frequency characteristics of the system, which will affect the stability. This paper analyzes the configuration of the grid-following converter and builds its small-signal model in detail.

Sensitivity Analysis and Small-Signal Stability of Grid Following Converters
TecnoLógicas, 2022 This article presents a small-signal study, based on a sensitivity analysis, of a voltage source converter (VSC) operating as a grid-following device. This type of operation is standard for integrating distributed energy resources directly into a primary grid without considering the control over specific variables (e.g., voltage and frequency), thus ...
