智能电源模块的三相逆变器设计
摘 要：随着电力电子技术的飞速发展，结合实际需求，设计效率高、稳定
性好、连接调试方便、具有良好人机界面、操作简单、安全可靠、智能运行的小
型逆变器将具有十分重要的现实意义。本文首先介绍了逆变器的现实意义，并给
出了逆变器的拓扑结构，通过仿真在 MATLAB/Simulink 软件平台下搭建了系统的
仿真模型，对后面的设计提供了数据支持和理论保障；该设计选用智能功率模块
(IPM)-STK5Q4U362J 作为逆变模块，应用 STM32F103 作为主控芯片进行了硬件电
路设计；软件控制设计介绍了逆变过程中采用的核心技术原理，即 SPWM 技术，
并对系统软件编程部分做了分析，详细介绍了程序设计中用到的各个寄存器及其
配置，给出了程序设计流程图；最终设计了基于频率开环的三相逆变器，测试结
果显示：该设计性能稳定、稳态精度高。

The Software Design of Three-phase Inverter Circuit
Based on Intelligent Power Source
ABSTRACT：With the rapid development of power electronic technology,
Combined with the actual demand, it has very important practical significance to
design efficient, stable, easy to connect, easy to operate, safe and reliable,
intelligent running small inverter.First of all, This paper introduces the
practical significance of the inverterthis, and introduces inverter
topology,through simulation, the simulation model of the system is built under
the MATLAB/Simulink software platform, data support and theoretical support are
provided for the following design. The design uses an intelligent power module
(IPM) -STK5Q4U362J introduced as the inverter module,STM32F103 is used as the
master chip to design the hardware circuit,Software design introduces the
principle of the core technology of the inverter in the process of SPWM
technology,this paper mainly analyzes the system software programming part,
introduces the various registers and configuration procedures used in the design
