“…As correntes de linha drenadas da rede CA pelo RHT são compostas pela soma entre as correntes requeridas por Ret-1 e as correntes impostas pelo conversor Boost que compõe a estrutura Ret-2, seguindo o mesmo princípio de imposição de corrente visto em [17]- [21]. Assim, as formas de onda das correntes de linha de entrada dependem das correntes impostas pelo conversor chaveado, as quais determinam a melhoria da DHT e a conformidade com as normas internacionais IEC 61000-3-2 e IEC 61000-3-4, conforme também pode ser observado em [22], [23].…”

This work presents the analysis and the development of the topological structure of a Three Phase Hybrid Rectifier, which offers the operational characteristics for sinusoidal line current imposition with high power factor and low total harmonic distortion of the current. This structure also provides a dc bus bar with regulated voltage using the innovative Series Voltage Compensation technique onto dc bus for both normal condition of grid supplying as for conditions of temporary balanced and unbalanced voltage sags onto AC grid. In order to corroborate with the exposed theory and Artigo submetido em 23/11/2017. Primeira revisão em 22/02/2018.

The results proved the efficacy of the proposed solution and demonstrated that it has great potential for application as power supply for DC loads suffering from voltage sags on the AC grid and for voltage stabilization on DC microgrids due to inherent intermittency of solar photovoltaic and wind energies.

“…The FBSRC is another suitable topology for high‐power battery charger applications. However, designing a gain curve with a wide range of output voltage variations is not easy [19–27]. For high‐frequency operations at low output voltage conditions, parasitical components seriously affect converter performance.…”

This study presents a high-efficiency battery charger with cascode output design. The output voltage is cascode comprising two parts: one is fixed and the other is variable. High efficiency can be achieved under a wide range of output voltage variations. This topology can increase the utilisation of transformer duty cycle and reduce the power loss. The constant current and constant voltage charging schemes can be achieved by the proposed cascode configuration for battery charger applications. A 3.3 kW laboratory prototype is implemented and tested. The experimental results verify the feasibility of the proposed scheme.
