Abstract

The invention discloses a bilateral LCC compensation network used for wireless electricity transmission and a tuning method for same and belongs to the technical field of wireless electricity transmission. A transmission circuit includes a transmitting coil 103, a first capacitor C1 whose one end is connected with the transmitting coil 103 while the other end connected with a compensation inductor, a capacitor Cf1 connected across two ends of the transmitting coil 103. And the first capacitor C1 and the compensation inductor are connected between the voltage source and the transmitting coil in series. The network also includes a receiving circuit including a receiving coil 104, a second capacitor C2 whose one end is connected with the receiving coil 104 while the other end connected with a compensation inductor, a capacitor Cf2 connected across two ends of the receiving coil 104 in parallel. And the second capacitor C2 is connected between a battery and the transmitting coil.

Description

technical field [0001] The invention relates to a wireless power transmission system, in particular to a bilateral LCC compensation network for wireless power transmission and a tuning method thereof. Background technique [0002] The concept of resonant wireless power transmission was proposed by Tesla more than 100 years ago. With the continuous development of power electronics technology in recent years, the cost of wireless charging devices has been continuously reduced, and the charging efficiency has been comparable to that of contact charging. Due to the convenience and safety of wireless charging, the related market is developing rapidly. Low-power wireless charging equipment has begun to be promoted in the fields of mobile portable devices and implanted medical devices. The power transmission power in this field varies from a few milliwatts to tens of watts depending on the specific application. In high-power wireless charging, the power transmission power can rea...
