With the development of smart grid, many wireless sensor nodes (WSN) used in monitoring grid equipment need continuous power supply. This work propose a multi-frequency array piezoelectric vibration energy harvester (PVEH) powering WSN based on the grid transformers vibration of 100, 200 and 300 Hz. The PZT bimorph with U shaped mass sturcture is design and opitimized by finite element simulation. The bonding method of epoxy conductivity and insulation is studied for PZT bimorph and aluminum packaged PVEHs. The equivalent circuit modeling and interface circuit of PVEHs are studied in LTspice simulation. Through the whole system design of the array PVEHs powered WSN circuit with LTC3331 chip, the WSN can run continuously in simultation and experimental verification. The feasibility of multi-frequency PVEH powered WSN is verified on the 500 kV transformer in filed operation. This research has important application value to the design of WSN self-power supply for smart grid.

This paper proposes a self-powered multiple piezoelectric (multi-PZTs) energy harvesting interface based on extensible parallel synchronized switching harvesting on inductor (PSSHI) rectification with power region optimization technique. The extensible PSSHI rectifier can accept multi-PZTs voltages input with arbitrary phase, thus addressing the charge conflict problem. The power region optimizer can assist the rectifier to operate within the high output power region. Meanwhile, all active devices in the circuit are powered by the harvested energy. Finally, the experimental results show that the average charging power of the circuit is 559.8W, and the energy conversion efficiency is 80.7%. Compared with the extensible PSSHI rectifier without power region optimization, the average charging power in this circuit is increased by 94%. Additionally, the experimental tests indicate that the interface circuit can completely realize cold start and self-power supply.

Due to its strong environmental robustness and high energy density, piezoelectric energy harvesting is considered one of the most promising methods to power wireless sensor nodes under extreme conditions. The interface circuit is essential to a piezoelectric energy harvester to reduce internal energy dissipation, achieve impedance matching, and improve energy conversion efficiency. Existing researches show that a parallel synchronized switch harvesting on inductor (P-SSHI) interface circuit compared with a standard energy harvesting (SEH) circuit can significantly improve the output power. Therefore, this paper proposes a self-powered optimized parallel synchronized switch harvesting on inductor (SP-OPSSHI) circuit, which adopts a new peak detection (PKD) switching circuit to replace the switches in the P-SSHI circuit. It can realize switch control without an external starting power supply, i.e., cold start. Compared with an existing self-powered PSSHI (SP-PSSHI) circuit, it can effectively eliminate the “second inversion” phenomenon caused by the parasitic capacitors of transistors after the voltage inversion process. The cause and effect of “second inversion” on energy harvesting are analyzed in this study. Then, the working principle and process of the optimized circuit are discussed, and energy harvesting under the ideal state is conducted. Finally, the SP-OPSSHI circuit is developed and tested. The experimental waveforms show that the SP-OPSSHI circuit compared with the SP-PSSHI circuit can significantly reduce the impact of parasitic capacitors in the energy harvesting process. The output performance of the SP-OPSSH circuit is tested with the variation of resistance. The experimental results indicate that the SP-OPSSHI circuit has an optimal load resistance of 350 kΩ, achieving a maximum harvested power being 2.91 times that of the SEH circuit.
