Power transmission control device, power transmitting device, non-contact power transmission system, and secondary coil positioning method |
摘要 |
A power transmission control device used for a non-contact power transmission system includes a power-transmitting-side control circuit that controls power transmission to a power receiving device, and a harmonic detection circuit that detects a harmonic signal of a drive frequency of a primary coil. A resonant circuit (leakage inductance and resonant capacitor) that resonates with the harmonic of the drive frequency of the primary coil L1 is formed in the power receiving device so that harmonic resonance occurs. The harmonic detection circuit detects the harmonic resonance peak of the drive frequency of the primary coil. |
