【摘要】：双极性高频高压方波电源是一种体积小,重量轻,精度高,动态响应快,技术含量高的开关电源,这些也基本是这类电源的主要特点,方波电源开关频率在40kHz左右。目前,高频高压交流电源涉足到诸多领域,应用前景十分广泛,在科研试验方面应用尤其突出,如：电力电缆、电力电容器耐压试验；静电除尘；放电水处理等。对高频高压交流电源的研究有很多,但对双极性高频高压方波源的研究却是甚少。本文对双极性高频高压方波源的基本工作原理、电路结构进行了分析,旨在研制一台频率为100-100kHz可调、幅值10kV的双极性高频高压方波源。本文主要介绍了典型高频高压方波电源的工作原理,该电源主要由几部分组成,包括：整流电路、升压斩波电路和高频逆变电路等环节,简单分析了全控型器件IGBT的工作原理和脉冲宽度调制技术的基本思想。据此设计了高频高压方波电源实物,并利用PSIM仿真软件对电源设计的主电路各部分如整流滤波电路、升压斩波电路、逆变电路等做了详细的仿真分析,重点为整流斩波电路增加负反馈稳压控制系统,做出了电路优化。最后通过实验的方法,对设计出的电路分两部分进行了实验分析：逆变电路和带反馈的整流稳压电路,其中针对逆变电路做出了能基本实现设计要求的电路板,并进行了相关的波形分析。实验制作基本的电路板结构,经验证基本满足要求。
[Abstract]:Bipolar high frequency and high voltage square wave power supply is a kind of switching power supply with small volume, light weight, high precision, fast dynamic response and high technology content. These are also the main characteristics of this kind of power supply. The switching frequency of square wave power supply is about 40 kHz. High frequency and high voltage AC power supply is involved in many fields, and its application prospect is very extensive, especially in scientific research and test, such as: power cable, power capacitor withstand voltage test, electrostatic dusting; The research of high frequency and high voltage AC power supply is much, but the research of bipolar high frequency and high voltage square wave source is very few. In this paper, the basic working principle and circuit structure of bipolar high frequency and high voltage square wave source are analyzed. In order to develop a bipolar high-voltage square wave source with adjustable frequency 100-100kHz and 10kV amplitude, this paper mainly introduces the working principle of typical high-frequency high-voltage square wave power supply, which is mainly composed of several parts, including: rectifier circuit. In this paper, the working principle of full control device IGBT and the basic idea of pulse width modulation technology are simply analyzed in the aspects of boost chopper circuit and high frequency inverter circuit. Based on this, the high frequency and high voltage square wave power supply is designed. The main circuit of power supply design such as rectifier filter circuit, boost chopper circuit, inverter circuit and so on are simulated and analyzed in detail by using PSIM simulation software. The emphasis is that rectifier chopper circuit increases negative feedback voltage stabilizing control system. Finally, through the experimental method, the designed circuit is divided into two parts: the inverter circuit and the rectifier circuit with feedback. The circuit board which can basically realize the design requirement is made for the inverter circuit, and the related waveform analysis is carried out. The basic circuit board structure is made by experiment, and it is proved that the circuit board meets the requirements basically.
