“…Conjugate matching uses switching devices (e.g., insulated-gate bipolar transistors, or IGBTs) and inductors for shaping the output voltage and current waveforms to alter the load impedance, thus enabling a higher power transfer for a wider vibration frequency range as compared to resistive matching. Since the switching devices should be switched synchronously with the displacement of the beam, it is inherently difficult to conform to rigorous timing control with simple circuitry and low power consumption [18,19]. However, resistive matching can only be realised if the impedance of the CB vibrating around the resonant frequency is mostly resistive [17][18][19][20].…”

“…where M is the modulation index of V carrier , thus correlating with SBC formulations in (14) and (15) due to T Z and T NZ involvement. From equations (19) and 20, it is clear that determining the inductor ratings (L 1 , L 2 ) and capacitor ratings (C 1 , C 2 ) involves the concise formulation of T Z,max , since it also affects the transient response of the qZSI [21][22][23][24][25][26]. Undesirable T Z,max precipitates increased ripple in inductor currents and capacitor voltages, as well as severe clipping of V boost .…”

The use of quasi-Z-source inverters (qZSIs) for DC-DC power conversion applications has gained much recognition when dealing with grid-tied renewable energy resource integrations. This paper proposes a novel self-powered dynamic system (SPDS) involving a piezoelectric vibration energy harvester (PVEH) using qZSI to establish interoperability with a DC load rated at 16.15 mW. Based on uncertain output performances from a piezoelectric cantilever beam (CB), the qZSI-based PVEH serves as a dynamic voltage restoration unit that establishes load-following synchronisation. It uses a proportional-integral based boost controller (PI-based BC) to generate strategic ordering of shoot-through voltage amplification into pulse-width modulation (PWM) gating sequences. The SPDS was modelled using two software based on commercially available product specifications: (i) COMSOL Multiphysics to mechanically design and optimise a CB. (ii) PSCAD/EMTDC to electronically design and integrate the qZSI with the optimised CB, while functioning as a testbed to model the SPDS against arbitrary wind speed and structural vibration frequency data collected from an above-ground mass rapid transit (MRT) train station in Khatib, Singapore. The acquired simulation results have depicted desirable transient responses at respective sub-systems, procuring fast settling-time responses, negligible steady-state error, as well as high efficiencies of 94.07% and 91.64% for the CB and SPDS respectively.

In this study, an energy harvester using the mechanical vibrations created by the airflow on piezoelectric transducers outside a vehicle was designed, produced and introduced. The introduced harvester has an energy production potential of μJ level. Given an energy power, very little power but long-term harvest was achieved. While the introduced vehicle was driven at speeds of 70, 90, and 110 km/h, energy production at location angles of 0 , 45 , and 90 was determined for each speed. Vehicle speed, location angle, airflow outside the vehicle, and harvester output were measured. Output voltage of the harvester was found to be directly proportional to vehicle speed. Output of the transducers was combined using a circuit topology that would maximize the output voltage. Thanks to this circuit highest output voltage was obtained from the location angle of 0. Thus, maximum output power was obtained at a speed of 110 km/h for 0 location angle. This research develops a new design method for efficient and practical energy generated by piezoelectric sensors placed on a vehicle from the vibration of the airflow around a moving vehicle. This energy harvester can meet the internal micro energy needs of the vehicle with an external battery.

“…Energy harvesting that overcomes the battery replacement issue has become an effective solution. Harvesters based on different energy sources have been reported, including vibration (piezoelectric [2], electromagnetic [3] and electrostatic [4]), electro-magnetic coupling (electric coupling [5], and magnetic coupling [6][7][8][9][10][11][12][13][14][15][16][17][18]), thermal [19], solar [20] and wind [21]. Solar and wind harvesters heavily rely on the weather conditions, so the energy storage element is bulky for a continuous power supply.…”

The current transformer (CT) harvester is an effective and efficient solution due to its higher reliability and power density compared to other techniques. However, the current of overhead conductor fluctuates from tens of to thousands of amperes, which brings two challenges for the CT harvester design. First, the startup current, above which the harvester can independently power the monitoring devices, should be as low as possible, so that the battery capacity can be reduced; secondly, the magnetic core should be ensured unsaturated in high current condition. This paper proposes a power conditioning circuit with comprehensive control to maximize the output power and prevent the core from saturation. A prototype that can deliver 22.5 W power with 200 A is designed, and a control strategy based on the finite-state machine is implemented. Experimental results show that the startup current for 2 W load is about 30 A, and the core power density at 60 A is 45.96 mW/cm 3 , both of which are markedly improved compared to the reported results of the same condition.
