[James] has a friend who teaches at the local community college. When this friend asked him to build a transformer coupling simulation, he was more than happy to oblige. Fortunately for us, he also ...

Everyone loves wireless power these days, almost vindicating [Nikola Tesla’s] push for wireless power. One reason why transmitting electricity this way is a terrible idea is the massive losses ...

Wireless charging system described by using the method of inductive coupling. In this paper, oscillation circuit converts DC energy to AC energy (transmitter coil) to transmit magnetic field by ...

Compared to wired, or direct contact, charging methods, inductive chargers are generally less efficient and require larger internal components to operate. In addition, the sensitive inductive coils ...

WIRELESS POWER ALLOWS THE TRANSMISSION OF ELECTRICAL ENERGY FROM A POWER SOURCE TO AN ELECTRICAL LOAD WITHOUT INTERCONNECTING WIRES. THIS PROCESS IS USEFUL WHERE INTERCONNECTING WIRES ARE INCONVENIENT ...

More than a century ago, Nikola Tesla studied high-power electromagnetic energy transfer without wires. Which raises the question: Why would Elon Musk, today’s tender of the Tesla flame, be investing ...
