摘要
逆变电源是电力电子中的关键技术,研究基于ARM32的单相逆变电源具有十分重要的工程实用价值。单相逆变电源主要采用的是全桥逆变结构,通过ARM32微处理器产生两路反向互补SPWM波,经过IR2109驱动模块输出四路互补的SPWM波,其分别推挽驱动全桥逆变结构中的四个MOS管的通断,完成电压直流到交流的转换,A/D采集模块实时监控逆变后的电流和电压,将采集数据反馈给ARM32,通过改变输出SPWM的占空比保护整个电路的安全。本设计基本达到指标要求,实现了用ARM32微处理器控制,将12V的直流电转换成50HZ、5V的正弦交流电,同时,增加了变频(50~100Hz)、变压(1~10V)的功能,实现了数字化控制。
Inverter is a key technology in power electronics.Therefore,it is of great theoretical significance and practical engineering value to study the design and implementation of ARM32 based single-phase inverter.Single-phase inverter power supply mainly adopts full bridge inverter structure,through ARM32 microprocessor to produces two lines of reverse complement SPWM wave,and by IR2109 driver module’s outputing four-road complementary SPWM wave,pushes and pulls driving structure of the whole bridge inverter respectively on and off the four MOS tube,completes voltage in dc-to-ac conversion and A/D’s acquisition of module’s real-time monitoring current and voltage of inverter after,will collect data then feedback to ARM32,by changing the duty ratio of output SPWM to protectes the safety of the whole circuit.This design basically meets the requirements of the index and realizes the conversion of 12 V direct current into 50 HZ and 5 V sinusoidal alternating current controlled by ARM32 microprocessor.At the same time,the functions of frequency conversion(50-100 Hz)and voltage conversion(1-10 V)are added increased to realize the digital control.
