Table 2 Capacitance values of four compensation circuits
From: Design of UAV wireless power transmission system based on coupling coil structure optimization
Compensation circuit | Capacitance of transmitting coil C1 | Capacitance of receiving coil C2 |
|---|---|---|
S-S | \( \frac{1}{\omega^2{L}_1} \) | \( \frac{1}{\omega^2{L}_2} \) |
S-P | \( \frac{\omega^2{L}_2^2}{\omega^4{L}_1{L}_2^2-{\omega}^4{M}^2{L}_2} \) | \( \frac{1}{\omega^2{L}_2} \) |
P-S | \( \frac{\omega^2{L}_2^2}{\frac{\omega^2{M}^2}{R_L^2}+{\omega}^2{L}_1^2} \) | \( \frac{1}{\omega^2{L}_2} \) |
P-P | \( \frac{\omega {L}_1+\frac{M^2}{L_2}}{\frac{M^4{R}_L^2}{L_2^4}+{\left(\frac{\omega {M}^2}{L_2}+\omega {L}_1\right)}^2} \) | \( \frac{1}{\omega^2{L}_2} \) |
