TL;DR: Experimental results validate the theoretical analysis and demonstrate the very good performance of the proposed discrete-time sensorless vector control.

TL;DR: In this article, a discrete-time adaptive current controller for grid-connected pulse width modulation voltage source converters with LCL filter is presented, where the damping of the LCL resonance does not depend on the grid characteristic since the adaptive feedback gains ensure a predefined behavior for closed-loop current control.

TL;DR: In this article, the authors proposed a high-efficiency bidirectional integrated zerovoltage transition (iZVT) pulsewidth-modulation (PWM) converter for dc-bus and battery-bank interface.

TL;DR: In this paper, a comparison among digital control techniques with repetitive integral action applied to voltage-source PWM inverters is presented, which can reduce steady state errors and distortions caused by unknown periodic disturbances, which usually result from the input source and output load.

TL;DR: In this paper, single and three-phase synchronisation methods based on optimum filtering theory are proposed to make the synchronisation signals less sensitive to these perturbations, which can be useful by also providing the amplitude, instantaneous phase and frequency of grid voltages.
