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.

Tuning Method of a Grid-Following Converter for the Extremely-Weak-Grid Connection [PDF]
IEEE Transactions on Power Systems, 2022 This paper proves that a grid-following converter can stably connect to a weak grid even short-circuit ratio (SCR) is 1. Root instability causes of this grid-following control are identified including fast control response, insufficient damping, and slow voltage support.

Analysis and mitigation of dead time harmonics in the single-phase full-bridge PWM converters with repetitive controllers [PDF]
, 2018 In order to prevent the power switching devices (e.g., the Insulated-Gate-Bipolar-Transistor, IGBT) from shoot through in voltage source converters during a switching period, the dead time is added either in the hardware driver circuits of the IGBTs or ...
