Power Supply Design Parameters Online Programming

This article aims to design a online programming power supply based on FPGA.Power supply design principles are presented, and on this basis,we develop the overall design of the paper and give details of the design content.This paper introduces the theory of the DDS,we designed the DDS components,such as phase accumulator,phase fluctuation module and the phase location module and drive with SOPC systerm.As a result, we combine the digital-to-analog conversion circuit with the filter circuit to realize the design of arbitrary waveform generator. On the basis of the arbitrary waveform generator, this paper designed the voltage and the power amplification circuit of the current two-way.The voltage amplification used floating power supply technology, and the current amplification used AC constant current source program.Matched with an arbitrary waveform generator, the thesis designed interactive system based on MATLAB GUI, the user can generate arbitrary waveform generator Arbitrary Waveform data send through the system, and set an arbitrary waveform generator output signal frequency, phase, resolution and other parameters.Finally,we debuged the power supply design.The results show that the power supply design basiclly achieved the design requirements.
