【摘要】 变频电源越来越多地用作标准供电电源,为电器提供优良的供电环境,便于客观考核用电器的技术性能。设计了变频电源的电参数测量系统,以TMS320F2812芯片为核心并结合高精度16位芯片ADS8364来实现;在时序方面采用CPLD来控制,同时实现了频率的跟踪和同步采样功能。最后结合实际电路,进行了系统软件方面的设计和仿真。实践表明:该设计完全可以达到预期的采样精度,满足对变频电源电参数测量的需要。更多还原

【Abstract】 The variable frequency converter is more and more used as the standard power source to examine the performance of the electrical instrument easily and make a good environment for it.Designed the electrical factors measurement system of variable frequency converter,which is based on TMS320F2812 and high precise 16-bit ADS8364?In the time sequence control respect,it uses CPLD to realize frequent tracking and synchronized sampling function.With the circuit design,software of the system was designed and simulated.Practice shows that the design achieves the sampling precision and meets the needs of measurement of the variable frequency converter.更多还原
