“…The signals obtained at the development board output have been used (Fig. 13) to control a bridge inverter [16], [17], with insulated-gate bipolar transistors (IGBT) ( Fig.12). Examining the waveforms, it is noted that, in the same time interval, two voltages have the same polarity and the third one has opposite polarity.…”

The FPGA (Field Programmable Gate Array) circuits contain programmable logic components and are increasingly popular in implementing the applications for obtaining and processing signals. FPGA represents a modern development trend in digital electronics. The integration in the work with students of this trend is a difficult task, but also useful, because many students face problems when they must use a design environment. The application of FPGA technology can be useful to students either for the laboratory work on advanced topics, or for obtaining skills to use an industry standard design environment. The purpose of this paper is to conduct studies on the need to integrate the FPGA digital electronics trend in the laboratory didactic activity of the students. As case study, we present the design of a control circuit and its implementation in a FPGA, i.e. on a Basys2 board with Xilinx programming environment.

<p>The continuously increasing demand for control on electric power equipment has led to the rapid technological development in various applications such as renewable energy, electric drives, and communication. Pulse Width Modulation (PWM) switching is an important technique to control the output voltage. PWM signals can either be generated using digital controller or analog controller. Digital controllers are widely used to generate PWM signals due to their reliability in solving complex algorithms within short amount of time. Multiphase boost converter is capable to overcome high input current ripple, current stress and semiconductor losses in conventional boost converter. This paper proposes a PWM switching scheme for multiphase interleaved converter using Field Programmable Gate Array (FPGA). The proposed switching scheme uses PWM switching technique that is implemented by programming Altera DE2-70 board. The duty cycle can be easily adjusted using assigned switches on the Altera board. For validation, switching frequency was set to 100 kHz, and then switching signal was observed using oscilloscope.</p>

“…Both buck and boost operations are obtained by controlling the shoot-through period of the inverter. The firing pulses for the DC circuit are obtained by comparing triangular waves at fundamental frequency and a constant DC line at various levels; for the inverter, the pulses are generated by maximum constant boost control with the third harmonic injection scheme, which is the same as that used for traditional Z-source inverters [19,20]. This scheme is preferred as it maintains constant shoot-through and produces high boost factor.…”

This paper presents a novel approach for power generation from rotating machines in textile mills using externally coupled repulsive magnets and a new stepped DC coupled Quasi Z-inverter. Power is obtained as a byproduct of the effective harnessing of rotational energy with the use of repulsive magnets. This derived power is stored in a battery arrangement and is retrieved, buck/boosted, and converted to multilevel AC voltage with the new stepped DC coupled quasi Z-inverter. The proposed inverter is powered by isolated voltage sources, uses fewer switches, and produces less distortion in the resulting multilevel voltage compared to its counterpart, and thus reduces the filter requirements.The derived AC power from the system can be used for light-load applications in textile mills, thus compensating for the energy demands. Simulation of the entire proposed setup is performed in MATLAB/Simulink and the results are presented. The repulsive force produced by the magnets is assessed with K & J Magnet software. To validate the simulation, experimentation is done using rotating machines available in the laboratory. The prototype model of the stepped DC coupled quasi Z-inverter is used to study the performance of the system and the results are evaluated. The optimum modulation index is identified for different numbers of sources at the input.
