| Sumario: | As the development of Industry 4.0 technologies, utilization of Internet-of-Things (IoT) devices also have increased. Along with increased demand, energy consumption of increased indus- try 4.0 technologies, have led researchers to concerns regarding the carbon footprint that these devices left behind. With development of piezoelectric energy harvesters (PEH), with suitable interface, energy generated from vibrational kinetic energy can be stored for later use. This development have motivated researchers in pursue for high efficient energy harvesters that can be used in low power application. In this paper, recent technological advances in field of power conditioning of PEH devices is examined and two fundamental approaches are analyzed and simulated. Popular due to its electrical characteristics, Synchronised Switch Harvesting on Inductor (SSHI) and Synchronized Electrical Charge Extraction (SECE) are two widespread methods used as an interface in PEH devices, with latter providing constant power output along the frequency range. Paper provides parametric evaluation of novel self-powered P-SSHI inter- face proposed by [8], along with application of this configuration to other interfaces, S-SSHI and SECE. Proposed NSP P-SSHI interface, have showed better output performance among all candidates with output power of 501 μW. Moreover, in this paper, impact of capacitance values in NSP configuration also examined, which was omitted in original paper. For experimental evaluation of the project, dedicated test-bench printed on PCB was manufactured. |
