The efficiency depends on several parameters, which also includes control modulation, used for excitation of the transmitter coil. However, how much the modulation technique impacts the efficiency is studied rarely. In this paper, we compare the three most popular control modulation techniques for transmitter voltage of a wireless power transfer system. First, the theory behind the methods is presented by highlighting the difference between them and their implementation. The methods are implemented, together with a linear PI control scheme, to evaluate the efficiency and performance of each of the methods. Finally, the practical tests were performed, under different output power levels, in order to evaluate the practical performance of each modulation strategy furtherMDPI20252025-01-08 13:41:36Članek v reviji91497UDK: 621.31COBISS_ID: 221190147DOI: 10.3390/electronics14010006ISSN pri članku: 2079-9292sl© 2024 by the authors
