  "textContent": "The present disclosure relates to a wireless charging transmitter system and a method for controlling the same. The system includes at least two transmit coils, configured to simultaneously transmit electrical energy to a receive coil; at least two transmit circuits, wherein each of the transmit circuits is electrically connected to each of the transmit coils, and is configured to supply a current to the transmit coil; and at least one decoupling circuit, wherein the decoupling circuit is connected to any two coupled transmit coils of the at least two transmit coils. By controlling N switches in a first compensation circuit and/or M switches in a second compensation circuit in the decoupling circuit to operate in a turn-on state or a turn-off state, compensation capacitors respectively connected in parallel to two terminals of a first inductor and a second inductor are controlled to be in an operating state or a non-operating state, such that a compensation capacitance connected in parallel in the decoupling circuit is dynamically adjusted. In this way, an equivalent mutual-inductance of the decoupling circuit may be dynamically adjusted according to a charging environment, which improves decoupling precision of the decoupling circuit and reducing power consumption caused by coupling.",
