This paper presents the modular multilevel cascade converter (MMCC) based on chopper-cells suitable to medium and high voltage systems without line-frequency transformers. This converter is characterized by a modular arm structure composed by cascaded chopper-cells with floating dc capacitors. The arm structure requires average voltage control and voltage-balancing control of the dc capacitors. This paper proposes a continuous model and a control method to achieve rigid and stable voltage control of all the floating dc capacitors under common operating conditions. The validity of the theory is confirmed by computer simulation and experiment.

Brazilian Power Electronics Conference, COBEP

作者： Luis G. G. P. de Castro Maurício B. R. Corrêa Cursino B. Jacobina Post-Graduate Program in Electrical Engineering - PPgEE- COPELE Electrical Engineering Department (DEE) Federal University of Campina Grande Campina Grande PB Brazil

This paper presents an approach that allows to apply space-vector modulation strategy to eliminate common-mode voltage in multilevel inverters. The strategy is based on the reduction of the space vector diagram and on the choice of switching states in which the common-mode voltage is zero. Results were obtained with a real-time simulator and an experimental platform of a cascaded inverter up to 11-level shows its effectiveness. The influence of dead-time over the algorithm performance is investigated too.

This paper proposes a 4.3 kW three-phase integrated PFC AC-AC resonant inverter for Induction Heating (IH) Application. This converter is composed by three independent resonant inverters with non-smoothed DC link that achieves high power factor operation. The magnetic coupling of the three coils was modeled by using the impedance matrix for characterizing the resonant behavior of the arrangement. The coils arrangement with weak coupling between coils is applied for induction water heater. Experimental results validate the modes of operation with ZVS and the converter performance in the entire power input range (PF and THD).

This paper presents two energy conversion systems with two-phase permanent magnet (PM) machine and a rectifier with reduced number of controlled switches. The topologies are conceived with the purpose of converting wind energy into electrical energy (i.e., a wind energy conversion system (WECS)) for low power applications. Compared with some three-phase generation systems with reduced number of controlled switches, the proposed topologies permit obtaining sinusoidal controlled machine currents, reducing dc-link voltage and dq currents low harmonic distortion.

The study of printed monopole antennas (PMA) with truncated ground plane has application in various types of technologies. This kind of ground plane, promotes an omnidirectional radiation pattern with broadband response and allows the antenna to suffer influence from nearby conductive material. This article presents the simulated and measured results of influences from a rectangular aluminum tube on a circular PMA that meets the UWB technology requirements. The results obtained indicate that the tube at a wavelength distance of 1/8? reduce the bandwidth by 50% in X-band (8 ~ 12 GHz), half power bandwidth HPBW is approximately 90° and gain of 6.92 dBi.

Thermoelectric (TE) modules are solid-state devices that convert directly thermal energy in electrical energy. However, they can undergo performance degradation due to thermal cycling. In the present study, a control-based test platform that is capable to apply specific thermal cycling pattern at periodic intervals is presented in order to evaluate performance degradation that influence the TE module lifetime. Using this test platform, some parameters and the figure of merit ZT of a commercial TE module are measured before and after thermal cycling application. An important feature of the proposed platform is that the applied thermal cycling is bipolar, that is, it is possible to apply positive or negative temperature difference and, through this, performance degradation would be observed after only 548 thermal cycles much lower than previous works. © 2015 IEEE.

IEEE Conference on Antenna Measurements & Applications (CAMA)

作者： Pedro H. V. Rocha Glauco Fontgalland PPgEE-COPELE Post-Graduate Program in Electrical Engineering Electrical Engineering Department (DEE) Federal University of Campina Grande (UFCG) Campina Grande-PB Brazil

In this paper the characteristics radiation of overhead power lines glass insulators is investigated. Two feeding possibilities are used to analyze the radiation effects. The first feeding point is placed on the cap of the insulator and the second one is connected to the pin. The reflection coefficient (S 11 ) for two insulators covering the band of 30 MHz to 1 GHz was measured. The measurements were performed on insulators with different conservation states: one has a metal frame in good condition and the other one has both cap and pin parts rusted. The measured results show bands with good impedance matching (30 MHz to 200 MHz). The cleaned insulator reached S 11 = -18.7 dB at 127 MHz while -10.87 dB at 121.2 MHz was obtained for the rusty insulator. These spectral bands can be used in the analysis of insulator's conservation state and its interference characteristics.

In this paper is presented a new printed monopole antenna, bio-inspired by jasmine flower, that meets the Federal Communications Commission parameters for ultra-wideband systems. The design of the printed monopole antenna in jasmine flower has developed from a printed monopole antenna with circular geometry, with comparison results. The measured results of bio-inspired antenna in the jasmine flower showed compatibility with the parameters required by the FCC for ultra-wideband technology. It obtained bandwidth of 9.75 GHz, half-power beamwidth of 148 degrees, omnidirectional radiation pattern, gain of 5.99 dBi, power spectral density below -41.3 dBm across the bandwidth of ultra-wideband technology, small pulse distortion, and constant group delay, with variations of less than 2ns.

This paper presents an open-end winding permanent magnet synchronous generator system with reduced controlled switch count, which may be applied to Wind Energy Conversion Systems (WECS). The configuration is obtained from the blend of a three-phase controlled rectifier (composed only of controlled switches), a non-controlled rectifier (composed only of diodes) and an open-end winding machine. A detailed model and a PWM control strategy of the systems, including the synchronism technique are presented to ensure the elimination of zero-crossover distortion normally caused by the use of diodes. Simulation and experimental results are also presented.

作者： Mota, Hilton De O. Vasconcelos, Flávio H. Electrical Engineering Post-graduate Program - PPGEE UFMG Centro Universitário de Belo Horizonte Belo Horizonte Brazil Electrical Engineering Department UFMG - Universidade Federal de Minas Gerais Belo Horizonte Brazil

This paper describes a system able to acquire, process and eliminate noise in continuous streams of data in real-time. The signal processing algorithms were based on the discrete wavelet transform and employ a new approach to deal with border problems, allowing to process the data continuously. The system was implemented using a DSP coupled to a digitizer through its external memory bus to guarantee deterministic behavior while maintaining some degree of flexibility in its configuration. The achieved performance and potential applications are discussed at the end of the text.
