摘要
介绍了以LM3S615为核心的逆变电源系统。采用了占空比可调的脉宽调制波(PWM)技术控制IGBT导通与关断,从而获得理想的交流电源。本系统主要由推挽拓扑结构的的DC/DC斩波模块,DC/AC逆变模块,以及主控制电路和外围接口电路模块组成。同时对系统的硬件电路进行了分析并给出部分软件流程框图。
LM3S615 is introduced as the core of the inverter power system in this paper.In order to obtain the ideal AC power,it uses PWM technology to turn on and shut off IGBT.This system mainly consists of the push-pull of topological structure of the DC/DC chopper module,DC/AC inverter module,and the control circuit module and peripheral interface circuit module.Meanwhile the system hardware circuit is analyzed and part software flow chart are introduced.
