为了提高交流电源的精度并降低复杂性,提出一种基于复杂可编程逻辑电路(complex programmable logic device,CPLD)的陀螺信号发生电路的设计方法。阐述了交流电源信号发生器的工作原理及其在系统中的功能,介绍了常规的信号发生装置的设计方法及其优缺点。基于某惯性平台交流电源系统,采用可编程逻辑器件设计了交流电源信号发生器,从CPLD的设计流程及交流电源信号发生器2个方面阐述了电路的实现,并给出了仿真及实验波形结果。分析结果证明:在高低温情况下,该方法的电特性完全满足指标要求,具有信号输出精度高、抗干扰能力强、体积小、设计修改方便、成本较低等优势。
This paper presents the design of a signal generator （SG） based on the circuit of complex programmable logic device （CPLD）, for the purpose of making the AC power supply more accurate and less complex. It illustrates the working principle of this single generator and its role in power system, and the design method, advantages and disadvantages of common single generator. Based on certain inertia platform AC power supply system, use CPLD to design AC power supply signal generator. It illustrates circuit realization based on CPLD design procedure and AC power supply signal generator. Put forwards the simulation and test wave result. Under high or lower temperature conditions, it is verified that this signal generator meets all the specifications required and has the advantages of high output signal accuracy, good interference résistance, small outline, flexible design and modifying, and low cost, etc.
