Embodiments of negative pressure wound therapy systems and methods are disclosed. In one embodiment, an apparatus includes a driving circuit that supplies a driving signal to a negative pressure source to cause the negative pressure source to provide negative pressure via a fluid flow path to a wound dressing. The apparatus furthers include a controller that adjusts a frequency of the driving signal supplied by the driving circuit according to a comparison of a previous magnitude and a subsequent magnitude of the driving signal while the negative pressure source provides negative pressure. Thetransfer of power to the negative pressure source can thereby be tuned to maximize an amount of power transferred to the negative pressure source. 本发明公开了负压伤口治疗系统和方法的实施例。在个实施例中，设备包括驱动电路，所述驱动电路将驱动信号供应至负压源，使得所述负压源通过流体流动路径将负压提供至伤口敷料。所述设备还包括控制器，所述控制器在所述负压源提供负压时，根据驱动信号的前幅值和随后幅值的比较调节由驱动电路供应的驱动信号的频率。因此，可以调整给所述负压源的功率传输，最大化传输到所述负压源的功率的量。
