摘要
用“开关预置式电压调节方案”控制的逆变电源具有输出谐波含量低、输出频率精度高、控制电路简单等优点，是逆变电源研究领域的热点。本文研制出一种基于双微处理器(MPU)控制的单相中频逆变电源控制装置，逆变电路基于开关预置SPWM波脉宽调制。文中重点从两个方面分析了逆变电源控制装置的工作原理和系统设计，包括逆变电源输出滤波器的设计、逆变电源变压器的设计、IGBT的控制保护等，用单片机通过软件编程生成SPWM调制波的方法、控制器硬件电路组成以及其它附属电路的开发设计等。经PSPICE软件仿真和小功率电路实验证明，“通过改变开关角而实现调节输出电压”的闭环设计方案是可行的。在仿真和实验的基础上，完成了逆变电源控制装置的硬件和软件，以及一个基于WINDOWS98操作系统的电源监控软件的开发和设计。
The inverter apparatus controlled by pre- set voltage adjustment project has the advantages of low harmonic content, high output frequency precision, simple control circuit. Therefore, this kind of project is the hot point in inverter power studying
field. The author designed and developed a single phase mid-frequency inverter control unit, which is based on dual micro- processor system. The inverter is modulated by pre-set SPWM pulse width wave. To show the designing and analyzing process of the control system, the article mainly discussed two parts. One is the power circuit part, which includes designing of the output fiher and the power transformer for the system, and also the way for IGBT controlling and protecting. The other is control system for the inverter, which includes the way of producing SPWM wave using microprocessor, the hard ware system of the inverter and the other assistant circuits. Tested by PSPICE simulation and small power experiment,the designing project "adjusting output voltage by changing on and off time of the SPWM" is practical. The author has completed development of the hard ware and soft ware for the control system based on the experiment. In the mean-time . a supervised VB software for the inverter based on WINDOWS98 operation system is also developed.
