Embodiment approach 1

[0029] figure 1 It is a diagram showing a configuration example of a resonance type power transmission system according to Embodiment 1 of the present invention.

[0030] like figure 1 As shown, the resonant power transmission system includes: a resonant transmitting power supply device 2 , a power transmitting coil 3 , a power receiving coil 4 , a receiving circuit 5 , and a load 6 . figure 1 Among them, the primary power supply 1 is connected to the preceding stage of the resonance type transmission power supply device 2 . The primary power supply 1 outputs direct current or alternating current. Furthermore, the resonance type transmission power supply device 2 and the power transmission coil 3 constitute power transmission side equipment, and the power reception coil 4 , reception circuit 5 , and load 6 constitute power reception side equipment.

[0031] The resonance type transmitting power supply device 2 converts the electric power (input power) output from the primar...

Abstract

A power transmission-side apparatus is provided with: a switching parameter detection unit (21) that detects a switching voltage in a switching element (Q1); and an abnormality detection unit (a first comparison unit (264a) and an abnormality determining unit (265)) that detects, on the basis of detection results obtained by the switching parameter detection unit (21), an abnormality due to a foreign material.

Description

technical field [0001] The present invention relates to power transmission-side equipment that transmits power at high frequencies. Background technique [0002] In a wireless power transmission system, if power transmission continues with a metal foreign object sandwiched between the power transmission coil and the power reception coil, eddy currents will flow through the foreign object. As the foreign matter, thin plate-shaped metal, aluminum foil (Aluminum foil), DVD (Digital Versatile Disc: Digital Versatile Disc), Blu-ray Disc, etc. can be mentioned. [0003] Therefore, conventionally known is a wireless power transmission system that controls power supply by determining the presence or absence of a foreign object between a power transmission coil and a power reception coil (for example, refer to Patent Documents 1 and 2). [0004] In the system disclosed in Patent Document 1, dedicated detectors such as a voltage detection unit and a current detection unit are install...
