Abstract
Firstly, through the knowledge of circuit, this paper determines the equivalent circuit diagram of wireless charging system, studies and analyzes the relationship between the physical quantities in the primary side loop (off-board circuit) and the secondary side loop (on-board circuit). The functional expression between AC is too complex, so the sinusoidal scale is used to show the above relationship and list the KVL equations. By solving the KVL equations, the functional expression of current in off board circuit and on-board circuit is obtained, the relationship between current, power supply voltage and load impedance is analyzed, and the variation model of transmission efficiency with respect to matching impedance and transmission frequency under the condition of complete resonance is established. Taking the emission frequency of 30 kHz as the constraint condition, it is obtained that the transmission efficiency corresponding to 10 experimental data under the condition of complete resonance is about 20%-2%.
