我们描述了一种用于仿真电磁感应型无线电力传输（WPT）设备的方法。该模拟器是基于有限差分，时域方法。为了减少计算时间，使用两个图形处理单元（GPU）作为电磁场计算的加速器。第一GPU计算非共振状态的电磁场，第二GPU计算共振状态的场。两个GPU之间只需要交换两个物理量：自感和磁耦合系数。电容器和负载电阻实际上作为集总元件连接到线圈。实验结果与仿真结果吻合较好。预计WPT器件的瞬态响应分析将成为可能，在未来使用这种模拟架构。
We describe a method for simulating an electromagnetic induction type wireless power transmission (WPT) device. This simulator was based on the finite-difference, time-domain method. To reduce computation time, two graphics processing units (GPUs) were used as accelerators for the electromagnetic field computation. The first GPU calculated the electromagnetic field for the non-resonance state, and the second GPU calculated the field for the resonance state. Only two physical quantities needed to be exchanged between the two GPUs: self-inductance and the magnetic coupling coefficient. Capacitors and a load resistance were virtually connected to the coils as lumped elements. The experimental and simulation results were in good agreement. It is expected that a transient response analysis of WPT devices will become possible in the future using this simulation architecture.
