A Batteryless low input voltage micro-scale thermo electric based energy harvesting interface circuit with 0.1V start-up voltage presents in this paper. The active technique and its components have been chosen such as MOSFET and thyristor to design the proposed DC-DC boost converter with low input voltage (i.e., 0.1V) for energy harvesting interface circuit. The minimum working voltage as low as 0.1V an input the equivalent voltage of thermoelectric transducer has been proposed to design the boost converter. This paper presents techniques for the systematic modeling, analysis, and design of interface circuitry used in the equivalent voltage of the micro-scale thermoelectric energy harvesting systems. In the development of active-based circuits, the DC-DC step-up (boost) converter with thyristor have been designed instead of mainly diode and other components because the forward voltage of diode is (0.7V) higher than the incoming input voltage (0.1V). Finally, the complete proposed energy harvester circuit have been designed and simulated using the PSPICE software. The proposed circuit is capable to step-up regulated DC voltage up to 3.75V. The efficiency of the proposed circuit is greater than 65% following the simulation results. This work has focused on the application of micro-devices Wireless Sensor Network (WSN) device can be operated without battery.

W artykule opisano oszczędnościowe źródło napięcia wykorzystujące jedynie siłę temoelektryczną. Układ elektroniczny startuje już przy napięciu zasilania 0.1V i potrafi wytworzyć wyjściowe napięcie o poziomie blisko 4 V. Jako zastosowanie układu przewiduje się możliwość zasilania czujników bezprzewodowych jedynie z baterii słonecznej.
