摘要

介绍一款高电压扫描电源的设计方案。利用两组H桥串联技术使得电源输出电压可高达700 V，采用闭环控制策略获得较好品质连续稳定的三角波或者正弦波电流波形。首先介绍了电源的设计思路，接着利用Simplorer软件对电源主回路及PWM (Pulse Width Modulation)控制回路进行了建模和仿真，最后给出了电源实际的调试结果，结果表明电源设计方案合理可行。

Abstract

Background: The scanning power for osteoporosis therapy device is required to be with high voltage output of great precision. Purpose: The design of a high voltage scanning magnet power supply is presented. Methods: Two H bridge series made the output voltage of the power supply as high as 700 V. The closed loop control strategy was adopted to produce continuous trigonometric wave or sine wave current waveform of good quality. The design idea of power supply was introduced

and then the simulation of main circuit and Pulse Width Modulation (PWM) control circuit was provided using Simplorer software. Results: Power supply design and test results were reported. The tracking error was about ±0.2%

and all the goals of this power design are realized. Conclusion: The actual tuning results of the power supply show that the design of the power supply is accomplished.Cited
