在本文中，物理尺寸的感应电能传输（IPT）功率垫上的动态IPT公路进行了探讨。以前的工作只集中在固定IPT充电器的大小，本文扩展了这种分析双D（DD）和DD正交为基础的电源垫。首先，创建窗函数（这里使用高斯分布拟合）以对高速公路上的各个主焊盘通电时的功率传输分布进行建模。一个分析表达式的开发，可以预测所得到的功率分布从激励多个初级垫，根据各个初级垫电流和物理尺寸的IPT垫之间的相位角。然后提出一个实际的设计示例，该示例显示了如何调整垫的大小，以允许向轿车和SUV（气隙范围为250-400 mm）传输10 kW的功率，而当它们沿高速公路沿着时，功率仅减少25%。
In this paper, the physical sizing of inductive power transfer (IPT) power pads on a dynamic IPT highway is explored. Previous work has focused only on sizing for stationary IPT chargers, and this paper extends this analysis for double-D (DD) and DD quadrature-based power pads. First, a window function (here fitted using a Gaussian distribution) is created to model the power transfer profiles when individual primary pads on the highway are energized. An analytical expression is developed that can predict the resultant power profiles from energizing multiple primary pads, depending on the phase angle between the individual primary pad currents and the physical sizes of the IPT pads. A practical design example is then presented that shows how pads could be sized to allow for 10-kW power transfer to sedans and SUVs (air gaps ranging from 250–400 mm) with only a 25% reduction in power as they drive along the highway.
