Projeto de um retificador Vienna com elevado fator de potência usando a técnica...
Santos, Kristian Pessoa dos; Santos, Cícero Alisson dos; Bascopé, René Pastor Torrico; Praça, Paulo Peixoto; Almeida, Bruno Ricardo deThe converters CA-CC are a most used converters in industry and be present in practically all electronic devices, illumination systems, laptops, biomedical equipment and others. However, this converter behaves as nonlinear load to electric system and producing a non-linear current and have high value of Total Harmonic Distortion (THD). To around this issue, the Power Factor Correction (PFC) is made using dedica...
Conversor CC-CC trifásico isolado bidirecional LLC ressonante utilizando uma té...
Santos, Kristian Pessoa dosThis work presents a theoretical study and design of an novel proposed of an isolated threephase DC-DC bidirectional LLC resonant converter using a technique of phase shift control and frequency modulation. For the mathematical analysis of the converter, a single-phase model was used considering only the fundamental components. In addition, all switches, diodes, inductors, capacitors and transformers were consi...
Gerador de impulsos de tensão usando um conversor boost em cascata para inspeçã...
Santos, Kristian Pessoa dosThis paper presents the study and development of a voltage impulse generator using a cascaded boost converter topology operating in Discontinuous Conduction Mode (DCM) which will be used for the inspection of grounding systems used by electric power companies. The output voltage of the converter is applied to the grounding system which behaves as a load. The signal applied to the ground was measured by the data...
