|
摘要
针对变频调速系统结构设计复杂、调试困难等问题,提出一种选用先进的PS12034功率模块与TMS320F2812型号的DSP芯片设计变频器的方法。该方法采用集成功率模块设计方案,选用的器件集成度高、外围器件少,与其他设计相比具有电路结构简单、系统调试方便等优势。采用规则采样法和三相异步电动机恒压频比控制算法编写控制程序,对设计的硬件系统进行调试和测试,测试结果表明:该硬件系统运行可靠,为后续进一步研究其他控制算法提供了硬件基础。
Aiming at the complex structure design and debugging difficulty of variable-frequency speed control system,a method is presented to design frequency converter by using advanced PS12034 power module and DSP chip of TMS320 F2812. The method adopts integrated power module design scheme which uses high integration peripheral devices with less peripherals than other designs. The advantages of the scheme include the simple circuit structure and convenient system debugging. The control program is compiled by using the regular sampling method and the constant voltage-frequency ratio control algorithm of three-phase asynchronous motor. The hardware system is debugged and tested. The test results show that the hardware system runs reliably,which provides reliable hardware foundation for the further study of other control algorithms.
