“…The advent of environmental energy harvesting technologies presents a viable solution to this dilemma. By continuously harvesting environmental energy and converting it into stored electrical energy for the system, the continuous operation of nodes can be ensured, gradually replacing the traditional high-cost battery replacement approach and becoming mainstream [9,10]. Environmental energy, encompassing diverse forms such as wind, thermal, and solar is limited in its applicability to transmission lines.…”

To effectively detect faults in transmission lines, monitoring the operating status of these lines is imperative. However, providing power to monitoring devices for transmission line status presents a significant challenge. In this research, a hybrid energy harvesting approach based on micro thermoelectric generator (MTEG) and Triboelectric nanogenerator (TENG) is proposed, and a theoretical model for MTEG-TENG hybrid energy harvesting is established. This study develops an integrated energy harvesting prototype, which incorporates oscillating-triboelectric nanogenerators (O-TENGs), MTEGs, and a power management control unit. This prototype not only harvests energy from the vibrations of transmission lines but also converts the lines thermal energy into electricity. The Experiment results show that the maximum open-circuit voltages of O-TENG and MTEG reach 80.3V and 1.094V, respectively. Compared to a single MTEG energy harvesting device, the prototype of the MTEG-TENG hybrid energy harvesting device demonstrates a 5.36% improvement in energy harvesting and battery charging performance. Consequently, this approach achieves self-powered monitoring with excellent stability and lower manufacturing costs. It provides an efficient and durable power approach for transmission line status monitoring devices.

“…So the power loss in the rectification diode can easily become significant especially for low voltage signal. Several methods was employed for the low voltage rectification, such as synchronous rectification using MOSFETs [18], synchronous switch harvesting on inductor [19] and charge pump technique [20]. However, increasing the output voltage is still beneficial for management circuit.…”

“…Passive PFC is low cost since it does not require active switches and complex control circuits but it cannot provide high power factors like active PFC, so the active type is widely applied for PFC. Various active PFC methodologies are available for boost circuits to bring high power factor ability with ease of control attracting more research on this topic [8][9][10][11].…”

This paper presents a new soft switching boost converter with a passive snubber cell without additional active switches for battery charging systems. The proposed snubber finds its application in the front-end ac-dc converter of Plug-in Hybrid Electric Vehicle (PHEV) battery chargers. The proposed auxiliary snubber circuit consists of an inductor, two capacitors and two diodes. The new converter has the advantages of continuous input current, low switching stresses, high voltage gain without extreme duty cycle, minimized charger size and charging time and fewer amounts of cost and electricity drawn from the utility at higher switching frequencies. The switch is made to turn ON by Zero Current Switching (ZCS) and turn OFF by Zero Voltage Switching (ZVS). The detailed steady state analysis of the novel ac-dc Zero Current-Zero Voltage Switching (ZC-ZVS) boost Power Factor Correction (PFC) converter is presented with its operating principle. The experimental prototype of 20 kHz, 100 W converter verifies the theoretical analysis. The power factor of the prototype circuit reaches near unity with an efficiency of 97%, at nominal output power for a˘10% variation in the input voltage and˘20% variation in the snubber component values.
