摘要：
Certain aspects of the present disclosure are generally directed to apparatus and techniques for wireless charging. One example apparatus generally includes a plurality of inductive elements and signal generation circuitry coupled to the plurality of inductive elements and configured to generate a plurality of signals, where at least two signals of the plurality of signals have different magnitudes. In certain aspects, the signal generation circuitry is configured to drive the plurality of inductive elements using the plurality of signals, where at least one first inductive element of the plurality of inductive elements is driven using at least one first signal of the plurality of signals having a first phase and at least one second inductive element of the plurality of inductive elements is driven using at least one second signal of the plurality of signals having a second phase different from the first phase.
