Abstract
A vector control scheme is presented for a three-phase AC/DC converter with bi-directional power flow capability. A design procedure for selection of control parameters is discussed. A simple algorithm for unit-vector generation is presented. Starting current transients are studied with particular emphasis on high-power applications, where the line-side inductance is low. A starting procedure is presented to limit the transients. Simulation and experimental results are also presented.

Minimization of Grid Current Distortion in Parallel-Connected Converters Through Carrier Interleaving

TL;DR: A synchronous reference-frame-based analysis is presented to estimate the grid current distortion in interleaved grid-connected converters with unequal terminal voltages, and optimum interleaving angle is shown to be a strong function of the average of the modulation indices of the two converters, irrespective of the application.

Common-Mode Filter Design for PWM Rectifier-Based Motor Drives

TL;DR: In this paper, a commonmode (CM) filter based on the LCL filter topology is proposed, which provides a parallel path for ground currents and also restricts the magnitude of the EMI noise injected into the grid.

Phase-locked loop for grid-connected three-phase power conversion systems

TL;DR: In this article, a phase-locked loop (PLL) is proposed for the power factor control of grid-connected three-phase power conversion systems, and the performance of the PLL is analyzed under distorted utility conditions such as the phase unbalancing harmonics, and offset caused by nonlinear loads and measurement errors.

Space Vector PWM as a Modified Form of Sine-Triangle PWM for Simple Analog or Digital Implementation

TL;DR: The analysis establishes that CSVPWM can be viewed as a modified form of SPWM, and leads to a simple method to implement CSVP WM, which serves to unify the understanding of triangle-comparison based P WM and space vector based PWM techniques.
