Planar Transformer for an X-Ray Source

It would be advantageous to reduce weight and size of high voltage power supplies, to increase frequency of pulses of high voltage, and to improve control of magnitude of high voltage. The embodiments of high voltage power supplies described herein can solve these problems. The high voltage power supply can be used with an x-ray tube. The high voltage power supply can comprise an array of planar transformers each defining a stage with an AC input and a DC output. Each stage can comprise a pair of flat, coil windings adjacent one another and including a primary winding electrically-coupled to the AC input and configured to induce a current in a secondary winding. At least two stages can be electrically-coupled together in series with the DC output of one stage electrically-coupled to an input of the other stage such that a voltage is amplified across the stages. 减小高电压电源的重量和尺寸、增大高电压脉冲的频率、以及改进对高电压量值的控制将是有利的。本文描述的高电压电源的各实施例可解决这些问题。高电压电源可以与X射线管一起使用。高电压电源可以包括平面变压器的阵列，每个平面变压器限定具有AC输入和DC输出的一个级。每个级可以包括彼此毗邻并且包括电耦合至AC输入
