Design Of Three Way AC Power Source On FPGA

In recent years, the power electronics technology is the rapid development of an electronic productdevelopment often requires a high performance, secure and reliable source. However, the current signalsource generally expensive, large volume weight as well as rudimentary interactive interface. Therefore, thepurpose of this design is to design a low cost and stable performance as well as flexibility and ease ofoperation the three-phase AC signal source.This design is the production of a FPGA chip based on Altera Corporation to design and debug, whichuses hardware description language to build the sinusoidal waveform module. waveform generator basedon DDS technology. Then digital output signal after the digital-to-analog conversion module is converted toan analog signal. After pre-amplification preamplifier and adjustment, power and voltage will be somewhatincreased. By attempting to change the traditional power amplification method, on the power amplifiermodule, the main circuit uses the analog circuit with the high-voltage transistor to amplify the signal,achieving a high power output and enhancing with a load capacity of the output port. Interactive interfaceuses a color touch screen instead of the traditional way of input, the input method is more simple andconvenient and improve the scientific and technological content. SOPC technology is used in the system,according to the design requirements, moderate CPU performance, a variety of peripheral interface devicesand NIOS embedded soft core drive resistive touch screen controller chip ADS7843and display thecontents of the set. To achieve the stability of the system is reliable and not to endanger the operator, it isnecessary to add protection circuits. When uncontrollable factors happen, timely response can protect thecore of the device and the safety of the operator of the circuit.This paper explores the feasibility of the overall design of the program and demonstrates the feasibilityof the best option, designs and debugs each module which has been modularized, the final experimentalresults meet the design requirements of the program in the beginning of this article.
