We present a mathematical model to simulate transcutaneous energy transmission systems. Treating such systems as resonant power electronic converters, we develop the equivalent circuit equations, for which the circuit variables are then expanded as Fourier series and a multi-frequency averaging method was applied. Keeping terms up to first-order, the analysis produces a dynamic and harmonic model describing these energy transmission systems. With appropriate values for the circuit parameters, numerical results are compared with those of the exact time domain model. This comparison verifies that our model can adequately represent to first-order such energy-transmission systems.
我们提出了一个数学模型来模拟经皮能量传输系统。将这些系统视为谐振功率电子转换器，我们开发了等效电路方程，然后将电路变量展开为傅里叶级数，并应用了多频平均方法。保留一阶项，分析产生了一个动态和谐波模型，描述了这些能量传输系统。通过为电路参数选择适当的值，将数值结果与精确时域模型的结果进行了比较。这种比较验证了我们的模型可以充分代表一阶能量传输系统。
