Disclosed are a wireless charger and a wireless charging system comprising the same. According to an embodiment of the present invention, the wireless charging system comprises: a pair of power transmission units arranged to face each other, and including a transmission coil and a soft magnetic member; and at least one power reception unit interposed between the pair of power transmission units, and including a reception coil and a soft magnetic member. According to an embodiment of the present invention, power can be transmitted to be equivalent to a wired charging method or higher during a unit time while utilizing the existing wireless charging technology, thereby reducing a time required for charging a mobile device. In addition, the leakage of a magnetic field can be minimized even if the transmission coil and the reception coil are misaligned. The loss of the mobile device can be prevented, and the mobile device can be charged without connecting a power source to the mobile charger as well. |
