STAND-ALONE WIND ENERGY CONVERSION SYSTEM WITH MAXIMUM POWER TRANSFER CONTROL
(Universidad de Tarapacá., 2009)
A Multiple-Reference Complex-Based Controller for Power Converters
(Institute of Electrical and Electronics Engineers, 2021-06)
A multiple-reference complex-based controller is proposed for three-phase power converters feeding nonlinear and unbalanced loads. The control scheme incorporates a stable multiple-complex coefficient filter with bandwidths ...
Application of the Z-scan technique to determine the optical Kerr coefficient and two-photon absorption coefficient of magnetite nanoparticles colloidal suspension
(AMER INST PHYSICSMELVILLE, 2012)
We investigate the occurrence of the optical Kerr effect and two-photon absorption when an oil-based magnetic Fe3O4 nanoparticles colloidal suspension is illuminated with high intensity femtosecond laser pulses. The frequency ...
On the Steinmetz hysteresis law
(ELSEVIER SCIENCE BV, 2008)
The behavior of the Steinmetz coefficient has been described for several different materials: steels with 3.2% Si and 6.5% Si, MnZn ferrite and Ni-Fe alloys. It is shown that, for steels, the Steinmetz law achieves R(2)> ...
Adaptive Power Factor Regulation under Asymmetrical and Non-Sinusoidal Grid Condition with Distributed Energy Resource
(2021-01-01)
Active and reactive power regulation, unbalanced current compensation, and harmonic current mitigation are the most significant functionalities typically embedded to a three-phase multifunctional grid-connected inverter. ...
Análise dos impactos das correntes harmônicas nas redes de distribuição causados pela grande penetração de geração fotovoltaica
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de ElétricaEngenharia ElétricaUTFPR, 2022-06-13)
In this work, the effects of harmonic currents in a distribution network system with several photovoltaic inverters were analyzed. In the first part, the inductivecapacitiveinductive (LCL) filter sizing methodology was ...
Perda por impairment de ativos e o valor de mercado de empresas brasileiras de capital aberto
(Universidade do Vale do Rio dos Sinos, 2017-05-29)
The present study aimed to investigate the determinants of asset impairment loss, the Brazilian companies listed on the BM&FBOVESPA, in the period from 2010 to 2014. Its importance is given from the law No. 11,638/09 that ...
