Der volle Inhalt der QuellePower electronics aims to condition and control energy from a source to a load. Power converters, such as DC-DC converters, generate a stable output voltage from an unstable input voltage. In the pursuit of miniaturization and increased power density, the use of a piezoelectric element for mechanical energy storage holds promising prospects, especially at frequencies on the order of MHz.The thesis aims to contribute to the field of DC-DC converters using piezoelectric resonators for mechanical energy storage. The goal is to propose regulation strategies and an integrated circuit for non-isolated piezoelectric DC-DC converters operating at multiple MHz. These converters are of significant interest as they eliminate the traditional magnetic component, thus favoring miniaturization and increased power density. The lack of high-frequency regulation is a gap that the thesis strives to fill.This thesis presents piezoelectric DC-DC converters, highlighting their importance in increasing power density. The state of the art of these converters is explored, providing an objective comparison of performance among existing topologies. A generic theoretical model for all piezoelectric DC-DC converter topologies is introduced, representing a significant advance in predicting the operating frequency, duration of each phase of the conversion cycle, and the maximum amplitude of the piezoelectric current as a function of transmitted power and the piezoelectric resonator used. An optimization study of these converters is also conducted to define the optimal operating frequency (the piezoelectric resonator to be used) and the optimal topology to implement, maximizing power density while minimizing losses for a given input voltage, conversion ratio, and output power.In this manuscript, a regulation strategy at a frequency of approximately 10 MHz based on five parallel control loops is presented. The validation of this strategy is discussed, highlighting the challenges related to simulations. The analog design process of the main blocks of each regulation loop is presented, as well as two power stages optimized for different output powers in XFAB06 technology. The final layout of the designed converter and simulations with manufacturing variations related to the integrated circuit and temperature are also presented. Realistic results are obtained, demonstrating the proper operation of the converter at around 10, 6, and 1 MHz.The next steps involve experimental measurements on the designed integrated circuit, a comprehensive theoretical study of regulation loops for different topologies, and the exploration of solutions such as an FPGA for regulation at around 10 MHz. The research aims to strengthen the robustness and flexibility of non-isolated piezoelectric DC-DC converters, paving the way for more diverse and efficient applications beyond the MHz range. In summary, this thesis constitutes an initial proof of concept for the development of more robust piezoelectric converters in terms of power density, low electromagnetic radiation, and compactness of the piezoelectric resonator

Der volle Inhalt der QuelleThe objective of this study was to increase the output current and power in a piezoelectric transformer (PT) based DC/DC converter by adding a cooling system. It is known that the output current of PT is limited by temperature build-up because of losses especially when driving at high vibration velocity. Excessive temperature rise will decrease the quality factor Q of piezoelectric component during the operational process. Simultaneously the vibration energy cannot be increased even if under higher excitation voltage. Although connecting different inductive circuits at the PT secondary terminal can increase the output current, the root cause of temperature build-up problem is not solved.This dissertation presents the heat transfer technology to deal with the temperature build-up problem. With the heat transfer technology, the threshold vibration velocity of PT can be increased and thus the output current and output power (almost three times).Furthermore, a comparison between heat transfer technology and current-doubler rectifier applied to the piezoelectric transformer based DC/DC converter was also studied. The advantages and disadvantages of the proposed technique were investigated. A theoretical-phenomenological model was developed to explain the relationship between the losses and the temperature rise. It will be shown that the vibration velocity as well as the heat generation increases the losses. In our design, the maximum output current capacity can increase 100% when the operating condition of PT temperature is kept below 55°C. The study comprises of a theoretical part and experimental proof-of-concept demonstration of the proposed design method

A closed-loop scheme of adaptive switched-capacitor converter (ASCC) is presented by combining a phase generator and non-overlapping circuit to realize the switched-capacitor-based (SC) step-down conversion for piezoelectric energy harvesting. In the power part of ASCC, there are two cascaded sub-circuits including: (i) Front: the bridge rectifier and a filter capacitor (Ci), and (ii) Core: 5-stage serial-parallel SC step-down converter and an output capacitor (Co). By using the front bridge rectifier, it converters the AC source of piezoelectric device into the DC source, and then harvests the energy to store in the filter capacitor Ci for building the DC supply Vs. The core 5-stage serial-parallel SC converter can provide 5 different step-down voltages (V_s/5,V_s/4,V_s/3,V_s/2,V_s), and with the help of the phase generator, perform an adaptive charging operation stage by stage (from the lower voltage to the higher one) for the protection of the battery load. Finally, the closed-loop ASCC is designed by OrCAD Pspice, and simulated for some cases: steady-state and dynamic responses (source/loading variation). Finally, we realize the implemental circuit, and all results are illustrated to show the efficacy of the proposed scheme.

This thesis presents a single-inductor triple-input dual-output(SI-TIDO) dc-dc converter for photovoltaic and piezoelectric energy harvesting systems. The SI-TIDO dc-dc converter uses buck-boost topology and can operate in continuous or discontinuous current modes that enhance the operation range of the converter. A new algorithm is proposed to share single inductor between all the inputs and outputs in one switch cycle. This algorithm determines light-load or heavy-load mode by current mode pulse width modulation control. Compared with conventional algorithms the proposed one saves a pair of compensator and mode detection circuits. Apart from regulating the output voltage to power the loading circuits, the converter also clamps the photovoltaic voltage to the maximum power point value. The fractional open-circuit voltage method is realized to track maximum power points by the capacitance divider circuit. Leakage reduction sample switch is used to extend the hold time of voltages. The peak efficiency of the proposed SI-TIDO buck-boost converter is 86.6%. The sampling cycle of the capacitance divider circuit is around 1.05 s. Each sampling takes 256 μs. Besides, a delay lock loop based zero-current detector(ZCD) is proposed. The proposed ZCD uses a delay lock loop to lock the time of pre-activation . Therefore, the power of proposed ZCD is lower full-time operation ZCD. The transient response of the ZCD is also faster than one point judgment ZCD because the ZCD have 100ns tolerance range.
