Wireless Energy Transfer

Abstrak  Energi listrik merupakan salah satu kebutuhan pokok yang sangat penting dalam kehidupan manusia saat ini, di mana sampai saat ini pengiriman energi listrik komersial tegangan rendah 220 volt masih mempergunakan kabel listrik. Salah satu cara pengiriman atau transfer energi listrik yang terus dikembangkan sampai saat ini adalah transfer energi listrik  wireless.  Transfer energi listrik  wireless  memiliki  beberapa  kelebihan  dibandingkan menggunakan kabel  yaitu  dapat  meningkatkan kenyamanan dalam penggunaan peralatan listrik  dan  dapat mengurangi jumlah sampah elektronik. Metode yang digunakan untuk  transfer energi wireless pada tugas akhir ini menggunakan  teknik  resonansi induktif medan elektromagnetik.  Pengguna membuat  dua buah  kumparan tembaga berbentuk selenoid yang digunakan untuk menghasilkan induktansi bersama. Rangkaian transfer energi listrik wireless terdiri dari dua yaitu rangkaian pengirim dan rangkaian penerima. Rangkaian pengirim terdiri dari rangkaian LC osilasi dan rangkaian penerima merupakan penggabungan beberapa komponen elektronika.  Realisasi alat bekerja dengan baik dengan pengaturan komponen yang sesuai. Namun pengaruh jarak dan sudut kemiringan antar kumparan sangat mempengaruhi nilai energi listrik yang mampu ditransfer. Semakin jauh jarak antar kumparan,  maka semakin kecil energi yang mampu ditrasfer, demikian juga dengan sudut kemiringan kumparan. Semakin miring sudut kumparan penerima, maka semakin kecil energi listrik yang dihasilkan. Kata kunci :  induktansi bersama,   kumparan tembaga, rangkaian pengirim, rangkaian penerima, transfer energi wireless. Abstract  Electrical energy is one of the basic needs that are essential in human life today,  where until today the delivery of electrical energy commercial low voltage 220 volts still using power cable. One way of delivery or transfer of electric energy are constantly being developed to date  is the transfer of electrical energy wireless. Transfer of electrical energy wireless has several advantages over using a cable that can increase comfort in the use of electrical equipment and can reduce the amount of electronic waste. The method used for  wireless energy transfer in this paper uses an resonance techniques inductive electromagnetic field. User create two shaped copper solenoid coils used to generate the mutual inductance. Wireless electrical energy transfer circuit consists of two circuits that the transmitter and receiver circuit. Transmitter circuit consists of a series LC oscillation andreceiver circuit is a merger several electronic components. Realization tool works well with setting the appropriate components. However, the effect of distance and tilt angle between the coil greatly affect the value of the electricity that is able to be transferred. The farther away the distance between the coils, the smaller energy capable to be transfer. as well as the slope angle the coil. The more sloping angle of the receiver coil, the smaller the electric energy is generated.  Key word : mutual inductance, copper coils, transmitter circuit, receiver circuit, wireless energy transfer

This manuscript investigates the effect of nonconservative electromechanical energy transfer on the onset of interwell motions in multistable piezoelectric energy harvesters. Multistable piezoelectric energy harvesters have been proven to outperform their linear counterparts when they undergo interwell oscillations. The conditions for interwell oscillations in such harvesters are generally characterized in terms of their potential energy function. This is accurate for a stand-alone mechanical oscillator but when the piezoelectric patches and a load resistance are included, a part of the kinetic energy supplied to the system is converted into electrical energy. In this manuscript, the Melnikov necessary conditions for interwell oscillations are derived, considering the effect of this nonconservative piezoelectric energy transfer. Through Melnikov theoretic analysis, it is shown that in a tristable harvester with all the three potential wells having the same depth, a higher excitation level is required to enable exits from the middle well to the outer wells when compared to the exits from the outer wells to the middle well. This is in stark contrast to a stand-alone tristable mechanical oscillator wherein interwell motions are simultaneously enabled for all the wells having the same depth.

Nowadays the groundbreaking tools of contactless energy transfer reveals new opportunities to supply portable devices with electrical energy by eliminating cables and connectors. One of the important applications of such technology is the energy providing to electric and hybrid vehicles, (EV) and (HEV). These contribute to the use of cleaner energy to protect our environment. In the present paper, after exposing the contactless energy transfer (CET) available systems, we examine the appropriateness of these systems for EV. After such exploration, it is shown that the most suitable solution is the inductive power transfer (IPT) issue. We analyze such procedure in general and indicate its main usages. Next, we consider the practice of IPT in EV and the different option in the energy managing in EV and HEV concerning battery charging. Following, we review the modes of using the IPT in immobile case and in on-road running. Following, the modeling issues for the IPT system escorting the vehicle structure are then exposed. Lastly, the electromagnetic compatibility (EMC) and human exposure analyses are assessed involving typical appliance.

AbstractAn exploding wire system has been experimentally studied by the observation of its plasma dynamics and the electrical energy delivered by the supporting circuit to the metallic wire. Plasma radial expansion has been obtained from visible light streak images, meanwhile electrical energy transfer dynamics was derived from the analysis of voltage and current traces of the exploding wire circuit. In these measurements, a significant portion of the electrical energy has been transferred to the exploding wire circuit during the plasma expansion, and lower limits for the resistivity during the plasma expansion confirm the existence of a central liquid or solid metallic core in addition to the expanding plasma.
