Design of pulse power supply based on super capacitor
ABSTRACT
The technology of pulse power supply has been developed greatly, and its application in various fields is becoming more and more extensive.. And the super capacitor as the main component of the pulse power, it has received the extensive attention of the academic community.
In order to meet the needs of different industries for higher accuracy and higher reliability of impulse power supply system, for the study and design of the pulse power supply of main circuit topology structure has become the industry an important content. This paper mainly introduces the based on super capacitor pulse power simulation experiment of pulse power system main circuit topology structure, the characteristics, and the use of saber circuit simulation software of the main circuit of simulation theory. The main job is:
1. The main circuit of the pulse power supply was established topology: introduced based on super capacitor pulse power supply circuit consisting of and and the parameters of basic element analysis and function of every basic element in the main circuit are analyzed, and point out the basis for the selection of the parameters of each element, through debugging based on the basic principles of the simulation software to determine the parameters of power circuit of the basic elements of the pulse.
