  • Patent number: 10886794
    Abstract: A power transmission apparatus oscillates alternating current power at a first frequency (f1) which is lower than a resonant frequency (fr) of the second resonator and at a second frequency (f2) which is higher than the resonant frequency (fr). The power transmission apparatus measures an inductance value Lin (f1) and an inductance value Lin (f2). The inductance value Lin (f1) is measured when the oscillation circuit oscillates alternating current power at the first frequency (f1), and the inductance value Lin (f2) is measured when the oscillation circuit oscillates alternating current power at the second frequency (f2). The power transmission apparatus calculates a coupling coefficient k by using an expression represented by k2=1?Lin(f2)/Lin(f1), to detect relative position of the second resonator to the first resonator on the basis of the coupling coefficient k.

  • Patent number: 10845858
    Abstract: A power supply device includes a power output terminal, a power converter and an electronic circuit breaker. In view of operation of the electronic circuit breaker, when an electric appliance that acts as a load is connected between the power output terminal and a ground terminal, the electronic circuit breaker is activated to output voltage from the power converter to the power output terminal so as to charge the electric appliance. When the electric appliance is done with charging and is removed, the electronic circuit breaker is deactivated to prevent voltage of the power converter from being outputted to the power output terminal. Thus, even if the power output terminal is exposed, the power output terminal won't output power to result in electric shock because of users' inadvertent contact when no electric appliance is being charged, thereby enhancing operational safety.

  • Patent number: 10848011
    Abstract: The present invention provides an apparatus and method for detecting a foreign object in a wireless power transmitting system. The wireless power transmitting apparatus measures an initial transmission power transmitted from the primary core block and performs foreign object detection on the basis of the initial transmission power, once it is found that an initial voltage of an output terminal of the wireless power receiving apparatus connected to an external load is within the range of a reference voltage. By performing foreign object detection while a wireless power receiving apparatus is in an initial setting completion state, before the output of the wireless power receiving apparatus is turned on, delay in detecting foreign objects may be reduced, and a risk due to heating of a foreign object may be avoided.

The preceding connection of the booster diode anode with the negative terminal of the low DC voltage source ensured by the pulse duration converter and second controllable switch correlates the booster diode switching time with the moment of closing the both controllable gates. Thus, the pulse noise present in the prior art designs is eliminated, and the level of interference emitted into the surroundings is decreased.

  • Patent number: 10800264
    Abstract: A vehicle control unit (e.g., a control unit for an automobile) receives feedback from an intelligent voltage/current sensor and a DC/DC controller. The DC/DC controller comprises a first switch for controlling power from a primary power source (e.g., low voltage power supplied from a high voltage battery). The intelligent voltage/current sensor senses power output from the primary power source. The vehicle control unit processes feedback from the intelligent voltage/current sensor and/or the DC/DC controller to determine if a failure has occurred in the primary power source. In response to determining the failure in the primary power source, the vehicle control unit disables the power from the primary power source using a second switch (e.g., a switch in a relay).
