This paper proposes an optimization of a piezoelectric energy harvesting system by using a maximum power point tracking (MPPT) method. A full-bridge rectifier is implemented with a MPPT unit to obtain maximum extracted power by controlling a DC-DC converter following the rectifier. By using the MPPT unit, the extracted power efficiency of the rectifier is always larger than 80% regardless of the load...
Nowadays, harvested energy from surrounding environment plays an important role in the human life. This green energy gradually replaced for traditional energy such as fossil energy. Several methods have been used to capture green energy from environmental source. One of the most popular method is using piezoelectric material to harvest energy from vibration source. A piezoelectric energy harvesting...
Today green energy plays an important role in human life; thus, many methods have been used to harvest green energy from the surrounding environment for the service of humankind. One of the most popular methods involves the use of a piezoelectric (PE) material to harvest energy from vibration sources. A PE energy scavenging system has two functional sections: a transducer, which converts potential...
