TL;DR: In this article, the authors proposed a new dead time compensation method for a PWM inverter, which can be easily implemented by feedforwardly adding compensation voltages to the output reference voltage of the synchronous d-axis proportional-integral current regulator.

TL;DR: In this article, a dual vector current controller is adopted as an ac-side current controller to reduce the ac-sensor active power ripple under unbalanced voltage conditions in modular multilevel converters (MMCs).

TL;DR: In this article, the authors proposed a model predictive control (MPC) method for modular-multilevel-converter (MMC) high-voltage direct current (HVDC) systems.

TL;DR: In this paper, a hardware in-the-loop simulation (HILS) system is proposed to develop and test control algorithms and operation strategies for a microgrid, which is composed of a real-time digital simulator (RTDS) for realtime simulation of the micro-grid, a prototype microgrid management system (MMS) under test, and a communication emulator for interface between the prototype MMS and the RTDS.

TL;DR: A novel scheme for the estimation of the equivalent series resistance (ESR) of the dc-link electrolytic capacitor in three-phase ac/dc pulsewidth-modulation converters is proposed for condition monitoring, where the recursive least squares algorithm is used for reliable estimation results.
