In the recent years, the global climate has aggravated too much mainly because of the excessive emissions of carbon dioxide. The UNEP and WMO have suggested the every country all over the world take actions to reduce the emissions of carbon dioxide and to make contributions to energy conservation. The international climate conference whose theme was "Last Chance to Save Our Human" was held in2009in order to relieve the burden of our earth in reduction of the greenhouse gas especially the carbon dioxide. The reduction of carbon dioxide emission has become a worldwide issue which every country in the world has put enough effort on. In China, due to the special conditions of our nation, we need to put more efforts into the utilization and research of carbon dioxide so that the problem of developing and environmental protecting can be realized at the same time.The lower energy consumption, high efficiency and convenient method has become a more common way to utilize the carbon dioxide in scientifically. One of an attractive ways to synthesize the high added-value products combining carbon dioxide is to use the negative ion as catalytic media. However, searching for the negative ion power source in high density becomes a shortage of conducting this kind of research. In order to do much further study, designing of a non-thermal plasma electronegative ion reactor power system is proposed in this thesis and the conditions of artificial simulation for producing negative ion is clarified based on the conception mentioned above. Furthermore, the feasibility of artificial simulation is testified by making a simple experimental circuit.During the design of negative ion power source, the phase-shift full-bridge ZVS converter is considered as the core topology by choosing the UC3875as the phase-shift resonant master control chip and also by selecting the IRF840as the main power switch tube. Then, phase-shift ZVS resonant circuit is manufactured by considering the design ideas mentioned above. In addition, the high frequency transformer is designed and selected as the core device through the whole circuit. The parameters of high frequency transformer are established at the same time. Finally, the original design of reaction-plant power source system is completed by optimizing the whole parameters of power system.
