Peak current mode control of a boost rectifier with low distortion of the input current for wind power systems based on permanent magnet synchronous generators

Abstract:

This paper presents a Peak Current Mode Control of a Boost Rectifier with Low Distortion of the Input Current for Wind Power Systems based on Permanent Magnet Synchronous Generators with variable speed operation. The Three-Phase Boost Rectifier is operated in Discontinuous Conduction Mode (DCM). It is shown that the DCM operation significantly reduces the Total Harmonics Distortion of the currents in the Permanent Magnet Synchronous Generator, increasing the Power Factor of the system, so that the vibrations and mechanical stress of the generator is minimized. The characteristics of the DCM Boost rectifier are studied considering: 1) The series resistance of the inductors; 2) The modeling and adjustment of peak current mode control yielding a stable loop; 3) The design of an input filter that reduces the switching noise in the currents of the generator.
