一、前言高压电源在通信系统中用来给微波管(例如行波管)、海底同轴设备及阴极射线管等供电,其它一般的应用则有激光、复印机、空调、静电喷涂、x射线管、静电吸尘等。根据负荷的种类,对高压电源的电压和容量的要求也是多样的。这里就容量10千瓦、电压100千伏以下的电源为对象,阐述一下近年来在小型化、高频化、高可靠度的要求下,所涉及的技术 I. INTRODUCTION High-voltage power supplies are used to power microwave tubes (such as traveling wave tubes), submarine coaxial devices and cathode ray tubes in communication systems. Other general applications include lasers, copiers, air conditioners, electrostatic spraying, x-ray tubes , Electrostatic dust and so on. Depending on the type of load, the voltage and capacity requirements for high voltage power supplies are also varied. Here for the capacity of 10 kilowatts, the following voltage 100 kV power supply for the object, elaborated in recent years in miniaturization, high frequency, high reliability requirements, the technology involved
