摘要： PROBLEM TO BE SOLVED: To protect inner electronic circuits from damaging without mounting expensive large-size high-resistance voltage parts, even if an abnormally high voltage is output from a coil because a portable terminal equipped with a non-contact point power transmission coil is exposed to a strong magnetic field from an electromagnetic cooker.
SOLUTION: A voltage division resistor 42 divides a voltage generated in a secondary transmission coil 14 of a cellular telephone terminal. A voltage comparator 50 compares a voltage value obtained by dividing a voltage generated in the secondary transmission coil 14 by the voltage division resistor 42 with a reference voltage value previously set for detection of abnormally high voltage, and transmits a separation signal to a separation circuit 43 when the voltage division value from the voltage division resistor 42 exceeds the reference voltage value. The separation circuit 43 is provided between the secondary transmission coil 14 and a rectifier circuit 44, and completely interrupts electric connection between the secondary transmission coil 14 and the rectifier circuit 44 when the separation signal is supplied from the voltage comparator 50.

摘要： PROBLEM TO BE SOLVED: To suppress heat generation due to deviation of center position of coils in non-contact power transmission and to suppress deterioration in transmission efficiency. SOLUTION: A cellular phone terminal is provided with a secondary transmission coil 14 for non-contact power transmission, and a leakage magnetic flux detection coil 42 for detecting leakage magnetic flux thereof.

摘要： PROBLEM TO BE SOLVED: To enable recharging after a battery of a load becomes a fully charged state by non-contact point power transmission, and realize the re-charging with ease. SOLUTION: When detecting that a battery 94 of a load 90 is fully charged, a power transmitter 10 transmits power while saving power on the basis of power lower than in usual power transmission, maintains the operation of a charging controller (charging control IC) 92 in the load 90 to enable re-charging based on the charging control function of the charging controller 92. Since when the re-charging starts, the load state of the power receiver 40 is heavy, the power transmitter 10 detects the load state and resumes the load state from a power saving power transmission to usual power transmission. If the power receiver 40 is detached during power saving power transmission, the power transmitter 10 senses this and stops continuous power transmission so as to prevent useless power consumption.

摘要： PROBLEM TO BE SOLVED: To highly accurately detect an inserted foreign matter between a primary coil and a secondary coil using simple signal processing while suppressing an increase in the number of components in a non-contact point power transmission system. SOLUTION: During usual power transmission, a power reception side control circuit (52) of a power receiver (40) turns on/off an NMOS transistor (TB3) to execute intermittent load modulation. A power transmission control circuit (22) included in a power transmission controller (20) of a power transmitter monitors an intermittent change of a load of the power receiver side during usual power transmission, and when an intermittent change in the load is not detected, the control circuit (22) judges that a foreign matter (AR) is inserted between the primary coil (L1) and the secondary coil (L2) and stops power transmission. Also, when the load (94) is in a heavy load state, the control circuit forcibly reduces the power supplied to the load (94), so that the power transmitter can detect the change in load due to intermittent load modulation.
