“…The THD is 4.6% and power factor is 0.98. As a comparison, in the topology presented by [21] for the semi-controlled three-phase boost, the power factor is 0.982 and THD is about 18%. In [28] using a boost as DC intermediate stage, the THD is 11.06%, while for the bridge rectifier diode it is approximately 27%.…”

“…In order to produce power over all wind speed some topologies applied to low power operating in discontinuous conduction mode (DCM) have been presented in the literature by [16,20,21] where the rectification is carried out by a bridge rectifier diode, or as in [22], where a rectifier diode plus a DC-DC boost converter is used [23] as shown in Figure 1. This is a simple, cost effective and higher-power-density solution [24].…”

“…To mitigate these problems, DCM boost rectifiers have been considered. Two approaches are available: single-switch solution [17,[26][27][28] as shown in Figure 4, and a semi-controlled boost rectifier [16,21,[28][29][30] as it can be seen in Figure 5. These topologies produce an output voltage higher than generator voltage; therefore they are not appropriate if a lower voltage is needed.…”

Abstract:A new application of the three-phase buck-resonant converter is presented in this paper. It is shown that the analyzed converter is suitable to operate as the rectifier stage in low power wind energy conversion systems (WECS) based on permanent magnet synchronous generators (PMSG) with variable wind speed. As main features, it presents a single controlled switch, simple implementation and control, and operates with a high power factor and low harmonic distortion over all wind speed ranges. The converter topology, its design equations and its operation are presented, as well as the simulation results of the PMSG based conversion system. From the analysis carried out in the paper it is concluded that the converter is indicated to be employed in distributed generation and hybrid systems where wind generation is associated with other sources.
