- W2963447387 abstract "In order to improve the intelligence and integration of Alternating current field measurement technology, an Alternating current field measurement excitation source system based on Field Programmable Gate Array (FPGA) is designed. The design principle of the excitation source system is the direct digital frequency synthesis, including the hardware circuit and the digital circuit. The hardware circuit realizes the function of digital mode conversion and produces sine signal. The digital circuit is programmed by hardware description language, which can be used to generate digital signals with adjustable frequency and phase. The results of ModelSim software simulation and experimental test show that the excitation source system can produce 47.68 Hz-48.8 kHz sine wave signal and the frequency resolution is 47.68 Hz. When the frequency and phase of the synthesized signal need to be adjusted, the synthetic signal parameters can be adjusted by the key. The system has the advantages of high efficiency, intelligence and high integration." @default.
