考虑当前光伏发电、风力发电等新能源逆变入网的需要,在比较了现有逆变器的基础上,针对低压小功率的逆变,设计了一种基于STM32的单相正弦波逆变器.该逆变器主要由控制模块、全桥式逆变模块、同步BOOST电路、信号采集与调理模块、信息显示模块、欠压过流保护模块等构成.逆变器采用SPWM正弦脉宽调制,经过IR2104产生两路反相的SPWM波,驱动4个开关管IRF540工作,并利用STM32完成电流/电压采样、调试和液晶显示的数据处理.经实际测式,该逆变器获得了较高的转换效率,较低的输出电压/电流误差.

Considering the current need of new energy sources inverter net including photovoltaic power generation and wind power, based on the comparison of the existing design of inverter and the inverter of low voltage, a single-phase sine wave inverter is proposed based on STM32, which mainly consists of control module, a full bridge inverter module, synchronous BOOST circuit, signal acquisition and control module, information display module, under-voltage and over current protection module. The system is modulated with SPWM sine pulse width, two reverse phase SPWM waves are produced with IR2104, and...
