Wireless Sensor Networks (WSNs) have existed for many years and had assimilated many interesting innovations. Advances in electronics, radio transceivers, processes of IC manufacturing and development of algorithms for operation of such networks now enable creating energy-efficient devices that provide practical levels of performance and a sufficient number of features. Environmental monitoring is one of the areas in which WSNs can be successfully used. At the same time this is a field where devices must either bring their own power reservoir, such as a battery, or scavenge energy locally from some natural phenomena. Improving the efficiency of energy harvesting methods reduces complexity of WSN structures. This survey is based on practical examples from the real world and provides an overview of state-of-the-art methods and techniques that are used to create energyefficient WSNs with energy harvesting.

“…The two PMOS transistors are cross-coupled with each other and the two NMOS transistors are controlled by operational amplifier with an offset voltage V OS . The input is a sinusoidal current source given by i P (t) = I P sin(2πf P t), where I P is the amplitude of current and f P is the excitation frequency [10]. This current source is in parallel with a capacitor C P and an internal resistor R P .…”

“…Figure 10 shows the output voltage and current waveforms of diode bridge AC to DC converter it is found that the output power is given by V ×I and is equal to 60.36µW. So that the efficiency of the AC to DC converter is found to be only 38.08%.The efficiency is less due to the forward conduction drop in the diodes [10]. Figure 11 shows the MOSFET bridge AC to DC converter in which the diodes are replaced by PMOS and Figure 12 shows the input current and voltage waveforms of MOSFET Bridge AC to DC converter.…”

“…This ensures the necessity of an AC to DC converter, which is capable of extracting more power from the transducer. Traditionally used diode bridge AC to DC converter suffers from forward voltage drop across the diodes which constitute the major part of conduction losses [3,4]. So that the power extracted from the transducer is reduced.…”

Original scientific paperHarvesting energy from the renewable energy sources plays a very important role in recent days. Researchers are using various methods to capture the energy for different sources. One of the most prominent methods of energy harvesting from vibrations is by using piezo-electric material. Piezo-electric vibration harvesting is smart mainly due to the simplicity of piezoelectric transduction and the piezoelectric systems can be easily implemented into a wide variety of applications. Due to wide range of AC output voltage and low power, the piezo-electric generator cannot directly prop up the AC or DC electrical appliances. Hence in the majority applications the AC signal created by this generator needs to be rectified. In this paper a new highly efficient MOSFET full bridge AC to DC converter for piezoelectric energy harvesting is planned, which enhances the power extracted from the piezo-electric crystal. The proposed AC to DC converter reduces the voltage drop along the conduction path and thereby increases the power extraction and conversion capability. The proposed circuit is replicated in PSpice software package and then in the experimental setup. The performance is evaluated and compared.Key words: LED lighting, Piezoelectric vibration energy harvesting, Power converter, Renewable energy Procjena učinkovitosti mosnog MOSFET ispravljača za napajanje LED rasvjete korištenjem piezoelektričkog sustava za prikupljanje energije. Prikupljanje energije iz obnovljivih izvora odigralo je važnu ulogu u recentnoj povijesti. Istraživači danas koriste različite metode za prikupljanje različitih oblika energije. Jedna je od najistaknutijih metoda prikupljanje energije vibracijama korištenjem piezoelektričkih materijala. Ovaj način ističe se jednostavnošću piezoelektrične vodljivosti, a sustavi se mogu jednostavno implementirati u široki opseg primjena. Zbog širokog raspona AC izlaznog napona i male snage, piezoelektrički generator ne može se direktno spojiti na AC ili DC električne ure aje. Stoga je za većinu aplikacija AC signal ovakvog generatora potrebno ispraviti. U radu se prikazuje planiranje nove visoko-efikasne topologije punog mosnog spoja MOSFET-a AC/DC pretvarača za piezoelektričko prikupljanje energije, koje pojačava prikupljenu energiju iz piezoelektričnog kristala. Predloženi AC/DC pretvarač smanjuje propad napona duž puta vo enja i time povećava prikupljanje energije i sposobnost konverzije. Predloženi sklop izra en je u PSpice programskom paketu, a zatim na eksperimentalnom postavu. Svojstva sklopa procijenjena su i uspore ena.Ključne riječi: LED rasvjeta, piezoelektričko vibracijsko prikupljanje energije, pretvarač snage, obnovljivi izvori
