Description

technical field [0001] The invention relates to a digital platform for controlling, analyzing and displaying a programmable AC power supply, and more specifically, to a digital platform for a programmable AC power supply based on FPGA, DSP and ARM and a control method thereof. Background technique [0002] Programmable power supply refers to the power supply whose certain functions or parameters can be controlled by computer software programming. It can conveniently simulate various power supply states and power supply distortion, and can conveniently measure and analyze power characteristics. It is widely used in research and development, production and other fields. . The traditional programmable AC power supply uses a high-speed digital signal processor (DSP) combined with peripheral devices to complete the system control function. With the development of power electronics technology, the functions and structures of programmable AC power systems are becoming more and mor...
