摘　　要：三相正弦波是应用比较广泛的信号之一。本文提出了一种利用PIC单片机控制D/A产生三相正弦波的方法,正弦调制波的产生采用查表法。经过仿真,产生的波形完全符合技术要求,证明了设计的正确性和可行性。并且系统结构简单,使用方便,具有较高的应用价值。Three-phase sine wave is one of the signals in wide range of application. This article proposed a means in which the PIC SCM control D/A chip to produce three-phase sine wave. Sine wave is generated by look-up table. Through simulation, the produced wave had totally met the technical requirements, and it certificated the correctness and the feasibility of the design. This system which has simple structure and is easy to use possesses higher value of application.
