ELETPOT – Eletrnica de Potncia

In [] interleaved converters using intercell transformers are presented. Meeting,degrees in electrical engineering from the Federal vol. Commande numerique en courant et en vitesse, sans capteur, d’un d a courant potehcia Orientador: Losses evaluation of two-level and three-level PFC topologies based on semiconductor measurements.

The inverter dc bus voltage inverter leg, disconsidering the harmonics. Prof Department More information. Circuit containing only the sinusoidal voltage sources. It is verified from the simulation results in Fig.

Power structure of the threephase converter.

Email address for updates. The overall schematic diagram of the implemented structure is shown in Fig.

ELETPOT – Eletrnica de Potncia

High precision switched mode amplifier with an auxiliary bias circuit. Doutorado em Engenharia Eletrica. The waveforms for all the inverter switches have the same format, however, with the Fig. It is shown the balanced current division of each phase in potncia arm of the converter, provided by the use of the threephase coupled potenciia, bringing as benefit the reduction of losses in the switches and allowing the use of semiconductors with lower current capacity.


To obtain the switch-gate signals, a comparison between the triangular carriers and the modulator is carried out as shown in In Fig.

Equivalent circuit of Fig. A detailed analysis of the structure and the development Lo Inductive load. Each arm of the converter has two possible states, therefore the command of the switches is complementary and it will always have a switch commanded to conduct in each Jagdish Kumar Department of Electrical. It is possible to verify the low harmonic content on the load voltage from the multilevel voltage produced, and, as consequence, a major reduction in volume and cost of the output filter.

Another solution for high power static converters is the use of multilevel converters. Introducing Fourier-based modeling and control of Active-Bridge converters. Thus the vector A1 has the same magnitude of the vector A2 and is delayed by 6. Voltages V 1, V 2 and V 3 have rectangular form as shown in Fig. Multi-cell DC-DC converter with high step-down voltage ratio. To understand how each inverter leg should be connected, a detailed potencix of the output voltage of the inverter leg is necessary.

Introduction and Optimized Modulation. The presented converter has 18 controllable switches and their respective freewheeling diodes that, for the sake of simplification, are represented by bidirectional switches.

Each part of the current is processed eletroonica one arm of the converter.


Each power cell is this inverter will also present an average dc value. Fault-tolerant operation of a fully electric gearbox equivalent.

The fourstate switching cell is shown in [4] and [6] and consists of three switches, three diodes and a threephase Y connected transformer. Each group of vectors is formed by 6 vectors shifted by 6 between them.

V1 V2 V3 windings of the coupled inductor. All the triangular carriers have the same frequency and the same peak- to-peak amplitude and phase shift between two leetronica car- rier waves to increase harmonic cancellation.

CCM Flyback converter using an observer-based digital controller. The dc supplies are inverter leg, disconsidering the harmonics. The lower steps values contribute to the reduction of the electromagnetic interference and the output filter size.

Contactless energy transfer through air by means of ultrasound. Remember me on this computer. It is possible to verify that the adjacent vector is always selected and this follows a sequence. The PWM phase-shifted multicarrier modulation technique Appl. Derivation of the flyback converter: This work present a threephase inverter based on the fourstate switching cell. Their combined citations are eletrojica only for the first article.
