摘　　要：为设计一种低功耗的数字化正弦逆变器,设计了以STM32单片机为控制核心的全桥逆变器,该逆变器采由单片机的高速定时器产生高分辨率的SPWM脉冲,通过光耦隔离和IR2111驱动芯片把SPWM脉冲信号对由IRF840场效应管构成的全桥电路实现斩波逆变,经过LC滤波电路,最后实现高压SPWM脉冲转换成交流电源。The paper introduces a design of the full bridge inverter based on the STM32 microcontroller as the controlling core in order to design a low power digital sine-inverter,which uses a high resolution SPWM pulse produced by the MCU＇s high speed timer,and operates the SPWM pulse into chopper inversion by the photoelectric coupler and IR2111 to amplify power with the help of the full bridge converter made of IRF840,with the LC filtering circuit,finally changing high voltage SPWM pulse into AC power.
