摘要:
逆变器是日常生活中必不可少的电力转换工具,针对传统逆变器输出电压固定、可调节性差、体积庞大、成本造价高、精度和稳定性达不到要求等问题,设计了基于单片机控制的宽频逆变器。介绍了宽频逆变器的系统组织架构,硬件部分搭建闭环控制电路,跟踪输出电压,对输出电压进行实时调控。软件部分根据调压过程设计分段式逐步逼近调压策略,采用递归程序设计思想,保证调节过程的快速、准确、稳定。设计屏幕显示,方便用户观察逆变器输出电压,通过串口输出,获取调压过程的连续性。结果表明:所设计的逆变器实现了3300 V以内电压自由调节,电压输出误差精度控制在1 V以内,调压时间控制在1 s之间。
Abstract:
Inverter is an indispensable power conversion tool in our daily life. In view of the problems of fixed output voltage, poor adjustability, large size, high cost, accuracy and stability of traditional inverters, the design is based on Microcontroller controlled broadband inverter. The system organization structure of the broadband inverter is introduced. The hardware part builds a closed-loop control circuit to track the output voltage and control the output voltage in real time. The software part designs the step-by-step approximation voltage regulation strategy according to the pressure regulation process, and adopts the recursive program design idea to ensure the fast, accurate and stable regulation process. The screen display is designed to facilitate the user to observe the output voltage of the inverter and output it through the serial port to obtain the continuity of the voltage regulation process. The results show that the designed inverter realizes free voltage regulation within 3300 volts, the voltage output error accuracy is controlled within 1 volt, and the voltage regulation time is controlled within 1 second.
