Abstract (en)

[origin: EP2555375A1] A voltage detector for detecting a voltage generated in a second resonant coil (110; 240) that is disposed to face a first resonant coil (240; 110) and that performs at least one of electric power transmission and electric power reception to and from the first resonant coil (240; 110) in a contactless manner by means of electromagnetic resonance includes: a first high-impedance element (510) having one end connected to one end of the second resonant coil (110; 240); a second high-impedance element (520) having one end connected to the other end of the second resonant coil (110; 240); a low-impedance element (550) connected between the other end of the first high-impedance element (510) and the other end of the second high-impedance element (520) and having an impedance smaller than each of those of the first and second high-impedance elements (510, 520); and an output terminal (560) for outputting a signal associated with a voltage applied across the low-impedance element (550). In this way, in the contactless power supply system employing the resonance method, the malfunction in the resonant coil is detected while suppressing an influence over the resonance state between the resonant coils and suppressing increase of cost.
