Saat ini perkembangan teknologi Wireless Power Transfer (WPT) atau transmisi daya nirkabel semakin meningkat dengan pesat. Penelitian dalam peningkatan efisiensi WPT pun semakin beragam, baik di sisi transmitter maupun di sisi receiver nya. Pada tugas akhir ini, penelitian untuk meningkatkan efisiensi WPT dilakukan di sisi transmitter yaitu pada bagian Power Amplifier (PA). Penambahan terminasi harmonik ketiga pada sisi output PA kelas E konvensional secara efektif mampu menurunkan nilai arus yang mengalir dari drain ke source, ...

This book investigates the utilization of harmonics in the permanent magnet (PM) or rotor shape to improve the torque density of PM brushless AC machines including three-phase inner rotor and outer rotor machines, five-phase machines, dual three-phase machines, linear machines, by means of analytical, finite element analyses, and as well as experimental validation.
The torque density can be improved while the torque ripple remains low in PM shaping utilizing the 3rd harmonic. In this book, ...

This monograph deals with theoretical aspects and numerical simulations of the interaction of electromagnetic fields with nonlinear materials. It focuses in particular on media with nonlinear polarization properties. It addresses the direct problem of nonlinear Electrodynamics, that is to understand the nonlinear behavior in the induced polarization and to analyze or even to control its impact on the propagation of electromagnetic fields in the matter.
The book gives a comprehensive presentation of the results obtained ...
