Journal ArticleDOI
Hybrid solutions for improving passive filter performance in high power applications
TL;DR: In this article, a variable inductance controller for a parallel hybrid active filter system is proposed to selectively synthesize multiple "active inductances" at dominant harmonic frequencies without affecting passive filter impedances at all other frequencies.
Journal ArticleDOI
Design of a New Cooperative Harmonic Filtering Strategy for Distributed Generation Interface Converters in an Islanding Network
Tzung-Lin Lee,Po-Tai Cheng +1 more
TL;DR: In this article, a cooperative harmonic filtering strategy for the interface converters of distributed generation sources is proposed, and a droop control method based on the reactive volt-ampere consumption of harmonics of each interface converter is implemented.
Journal ArticleDOI
A Cooperative Imbalance Compensation Method for Distributed-Generation Interface Converters
TL;DR: In this paper, a droop control technique for imbalance compensation within the three-phase AC distributed generation system is proposed for micro-grid converters, which allows even sharing of imbalance current among various converters.
Journal ArticleDOI
Common-Mode Voltage Reduction Pulsewidth Modulation Techniques for Three-Phase Grid-Connected Converters
TL;DR: In this article, the performance of a three-phase voltage source pulsewidth modulation (PWM) converter with the grid interfaced photovoltaic energy conversion system being the main application is investigated thoroughly.
Proceedings ArticleDOI
Hybrid solutions for improving passive filter performance in high power applications
TL;DR: In this paper, a synchronous reference frame based controller implements the dynamically varying, negative or positive inductance, by generating active filter inverter voltage commands, which can selectively synthesize multiple active inductances at dominant harmonic frequencies without affecting passive filter impedances at all other frequencies.
