Design of Magnetic Resonance Wireless Power Charging System for Unmanned Aerial Vehicle with GaN HEMT

Magnetically coupled resonant multi-frequency and multi-load wireless power transfer system with load-isolation

“…Case 5: 𝑀 12 ≠ 0, 𝑋 1 ≠ 0, 𝑋 2 = 0. RX1 is tuned at 𝜔 2 and RX2 is tuned at 𝜔 1 , then the ratio of 𝐼 (5) 2 and 𝐼 (1) 2 can be expressed as:…”

“…where 𝐼 (5) 2 is the current of 𝑅 𝐿2 under the influence of crosscoupling and inter-frequency interference. If the conditions shown in Eq.…”

“…Magnetically coupled resonant wireless power transfer (MCR-WPT) technology is widely used in implantable medical equipment [1,2,3], unmanned aerial vehicles [4,5,6], household appliances [7,8,9], underwater working equipment and electric vehicles [10,11,12,13] due to its clean, convenient, and safe advantages. Until now, many charging standards are developed for WPT systems such as A4WP, Qi and PMA and there are some differences among them like the operating frequency [14,15].…”
