Wireless Power Transmission using LC Cancellation

Wireless power transmission technology enables flexible comfortable supplying energy needs to electric devices. However, the wireless power transmission technologies that use the magnetic field resonance method have various problems. Much of the research is often focused on the efficiency between resonators. The relationship between the internal resistance and efficiency is not clear. The efficiency at high output power is not well understood. Practically adding an internal resistance as an equivalent of both of rectifier and inverter losses is important for efficiency calculation. Even if the wireless power transmission has high efficiency it is not suitable for practical use if the output power rating is very small. We can increase transmission power in accordance to the principles of the LC cancellation by using the resonance phenomenon even at a small coupling coefficient.
