In this paper, a seriesly connected three phase bipolar symmetrical voltage multiplier (VM) is proposed, which is a novel VM for X-ray power supply. It consists of three single phase bipolar symmetrical VM, which are connected in series at their smoothing columns. The charging and discharging process occurs six times in a cycle and the frequency of the output voltage ripple is six times as large as the drive signal frequency. The proposed VM has three times larger output voltage and three times smaller ripple factor as compared to single phase bipolar symmetrical VM, and smaller voltage drop and faster dynamic response than those of the series connected three phase symmetrical VM. The simulation is provided to show the feasibility of proposed VM.
本文提出了一种串联连接的三相双极对称电压倍增器（VM），它是一种用于X射线电源的新型电压倍增器。它由三个单相双极对称电压倍增器组成，这些倍增器在其平滑柱处串联连接。充电和放电过程在一个周期内发生六次，输出电压纹波的频率是驱动信号频率的六倍。与单相双极对称电压倍增器相比，所提出的电压倍增器输出电压大三倍，纹波因数小三倍，并且与串联连接的三相对称电压倍增器相比，具有更小的电压降和更快的动态响应。提供了仿真以证明所提出的电压倍增器的可行性。
