摘要
针对有些变频器复杂的工业安装环境及节约成本的考虑,提出一款基于STM32的低成本矢量变频器的设计方案。给出了系统的硬件和软件的组成;硬件设计在满足系统的基本功能的同时,优化了空间布局,使系统体积小,重量轻,便于安装。阐述了空间矢量脉宽(SVPWM)原理及其在STM32上的实现方案,同时结合总线技术,来达到精确控制分散的系统的目的。最后通过实验表明,系统谐波少,实时性好,具有良好的节能效果与可靠性。
In view of the disadvantages of some complex industrial installation environment and saving cost in general inverter,a simple vector control inverter which based on STM32 is proposed.The design of hardware and software were given.The hardware optimized design of it’s structure,so it more smaller、lighter and easy installation.The principle of SVPWM modulation and it’s realized on STM32 were described.Thus it combine with field-bus technology can bring flexible and precise control in disperse system.The experimental result show that the system has less harmonic ware,real time control function,energy-saving and reliable.
