In this work the VSI structure is analyzed in Synchronous Active Front End configuration (SAFE). An analysis on power losses and thermal behaviors of the SAFE compared with its base version (AFE) is given. In these structures, due to the parallelization in current, the number of AC link reactors grows up with the number of interleaved converters. For this reason, at the end, an investigation on the...
In this paper, considerations on converter inductor design in PWM back-to-back converter based on Synchronous Active Front End (SAFE) are discussed. This is considered one of the most efficient converter topology that successfully manages the hard trade-off between high power size and power quality requirements at the Point of Common Coupling (PCC). In renewable energy, in wind farm, this trade-off...
With the request of renewable energy also the size of the wind turbines is growing. The converters used to connect them to the grid have to transfer a big amount of captured power. Since they handle high power, the switching devices work with a low switching frequency. This results in a high harmonic distortion of the injected currents and the need of big passive filters on ac side. In order to improve...
