输入线圈根据分析，应该是两个独立线圈，各占一半，磁场在水平方向互相抵消，但是在垂直方向有同极性的磁场向上下方向辐射，因此输出线圈也应该是两个线圈，在垂直方向磁场互相抵消，只有水平方向的有辐射磁场，因此输入线圈应该还有另外一对低电阻的线圈用来补充变化的磁场来抵消输出线圈辐射的水平磁场，因为输入线圈是水平方向耦合，因此电感很小，只需要很小的电压就能提供的很大的电流匝数乘积。
或者输出线圈各有一个双线并绕的输入线圈，这个输入线圈是高电阻的，用来为输出线圈线圈提供电压，而输出线圈的安匝乘积是由另外的水平方向的输入线圈提供，由于水平方向线圈是磁场互相抵消结构，因此只需要很小的电压就能提供很大的安匝乘积，也就是只需要克服铜损。似乎这种更符合VTA结构。

According to the analysis, the input coil should be two independent coils, each accounting for half. The magnetic field cancels out each other in the horizontal direction, but there is a magnetic field with the same polarity radiating upwards and downwards in the vertical direction. Therefore, the output coil should also be two coils, with the magnetic field canceling out each other in the vertical direction, and only the horizontal one has a radiating magnetic field, Therefore, there should be another pair of low resistance coils in the input coil to supplement the changing magnetic field and counteract the horizontal magnetic field radiated by the output coil. As the input coil is horizontally coupled, the inductance is very small, and only a small voltage is needed to provide a large current turn product.

Alternatively, each output coil has a dual wire parallel wound input coil, which is high resistance and is used to provide voltage to the output coil. The ampere turn product of the output coil is provided by another horizontal input coil. Due to the magnetic field cancellation structure of the horizontal coil, only a small voltage is needed to provide a large ampere turn product, which only needs to overcome copper loss. It seems that this is more in line with the VTA structure.
