Full textThe satellite payload evolution will have a great impact on power amplifier efficiency, redundancy and flexibility. Solid state power amplifiers (SSPA) should be used to replace traveling wave tubes (TWT) but power combining techniques are necessary as SSPA output power levels are lower than TWT. The radial power combining technique is well suited for spatial applications. It consists in placing amplifiers around a radial waveguide to feed amplifiers with equi-magnitude and equi-phase signals. Transitions between various propagation structures (coaxial, rectangular, radial, planar) were optimized and tested and a new radial 16-way power divider-combiner including planar structures for SSPA mounting (MMIC) was designed. An original mechanism to balance MMIC phase dispersion was successfully implemented in the divider-combiner structure

Full textThis work concerns the design, realization and characterization of a control transformer for insulated gate power switches, the transformer providing galvanic isolation between driving stage and power circuits. The aim of the work was not to respond to a precise specification but to develop a new technological path for the realization of an integrable planar transformer. The main characteristics of such transformer are: - high inductance (ratio of inductance / area occupied as large as possible); - low series resistances; - a capacitive coupling between primary and secondary as small as possible. These constraints guided us to study a planar transformer with magnetic layers whose primary and secondary windings are buried in the magnetic material in order to reduce the air gap. The Face to Face structure was chosen with a 45 ° offset between primary and secondary windings. After a numerical study, windings buried in a ferrite material were fabricated separately and then assembled to give rise to the transformer. Many technological steps: femtosecond laser micromachining, copper deposits by sputtering, photolithography, planarization, chemical etching ... have been implemented. Thus, the transformer produced consists of a stack of magnetic, conductive and insulating layers. It has been characterized from very low frequencies up to several tens of MHz. The measurement results obtained are close to simulation results, the bandwidth of the transformer extending from 20 kHz to 7 MHz

Full textThis thesis work aimed at realizing efficient, stable, and reproducible photovoltaic perovskite solar cells, and to achieve a good understanding of the cells functioning. In Chapter 1, we present the context of the research on solar cells and PSC components as well as a description of the main techniques employed for the device characterizations. Chapter 2 provides a comparative study of two different CH3NH3PbI3 deposition techniques (1-step and 2-step). It is clear that both of them are suitable for the preparation of PSC which resulted in more than 17% PCE. In Chapter 3, we have thoroughly studied the two main kinds of organic hole transporting materials: molecular and polymeric. We have also investigated the doping effect on these HTMs. Through impedance spectroscopy measurement, we could clearly see that doping is really important to get high efficiency for Spiro-OMeTAD cells, while the improvement was less significant in the case of P3HT cells. In Chapter 4, we have investigated several new carbazole derivatives as hole transporting materials. These molecules ranged from the big dendritic core B186 to the DMs and iDMs series with lower molecular weight. B186 and iDM1 showed the highest efficiency at 14.59% and 15.04%, respectively. In Chapter 5, we have studied a simple planar structure of PSC by incorporating a wide bandgap n-type semiconductor SnO2 as the hole blocking layer. Planar cells have been prepared using this layer combined with MAPI(1)-SOF and FAMA perovskites. With FAMA absorber, the devices were highly efficient with a maximum PCE of 18.2% and were almost hysteresis-free (6.7% HI) while, with MAPI(1)-SOF, the obtained efficiency was 15.2% with higher hysteresis

Full textThe open loop control is widely used by the digital systems to facilitate the integration in complex systems because no sensor is needed. The research is based on digital actuator which is composed of a mobile part and a fixed part. The actuator moves between the discrete positions. The discrete displacement consumes low energy, which is controlled by impulse only needed to switch the actuator between the discrete positions. However, the stroke of digital actuator is fixed at the manufacturing. So the digital actuators array is used to obtain variable strokes. A digital actuators array used here with a structured plate is applied as a 2D planar conveyance. Firstly, an actuators array composed of 25 elementary actuators with a flat plate is studied. The simulated results are compared with the experimental results. Then another actuators array composed of four elementary actuators with a structured plate is designed. The design and the plate displacement are firstly presented. Then the prototype of the conveyance is fabricated with laser cutting machine and 3D printer. The experiment is then tested in one direction to study the plate displacement. The open loop control is simple by using current impulse. The operation can be well functioned which is observed during the experiment. The experimental results are compared with the theoretical results
