摘要
虚拟仪器技术是计算机与测试技术相结合的产物。本文设计和实现了一种基于LabVIEW的SPWM信号发生器。利用LabVIEW编程产生载波频率和调制波频率及死区时间均可调的三相六通道SPWM波,并对其谐波进行分析。实验证明,该信号发生器具有设计简单、操作灵活的特点。
The technology of virtual instrument is made up of computer and measurement technology. The design and realization method of a SPWM signal generator based on software LabVIEW was discussed in detail in this paper. The generator programmed by LabVIEW can generate three phases and six channels SPWM signals, whose dead-time and frequency of carrier signals and modulation signals can be easily regulated. And the test results indicate that the signal generator is simply designed and can be well manipulated.
