| The research realm of switch power supply involves an electric power electronics and the automatic control waits a lot of technique realms. Among them, the soft switch technique is in recent years of a popular topic. Soft switch technical application can make the switch power supply have higher efficiency and lower electromagnetism interference.The RCC electric circuit is the anti- arouse type that we usually point from sudden change a machine, the work mode of transformer(keep can electricity) is placed in critical appearance, can conveniently carry out an electric current control, is a single extremity system on the structure and easily get quickly stable of respond to, extensively applied in the 50 Ws following switch power supply. It of the weakness is to output power smaller, its work frequency with output the variety of electric current and importation electric voltage change more and greatly. And opposite in it of weakness, the RCC advantage is also more outstanding. BE that the electric circuit structure is simple first, need a handful of spare parts can get the appropriation chip then can carry out of the electric voltage output function and have very high sex price a ratio. If we can overcome it of weakness, can make the RCC electric circuit get an extensive application, create a very big economic performance.This is exactly the mission of this thesis, this thesis is to carry on a thorough research to the RCC electric circuit, complete the only specialized chip then can carry out of the quasi- Xie flap a switch operation, let the RCC electric circuit work to flap appearance in the quasi- Xie .Raising an efficiency thus, providing for the RCC extensive application may.Finally combine textual theories, designed a high voltage of 130 Ws, this switch power supply work flaps appearance in the quasi- Xie and carried out a soft switch. From the as a result see of the test, the function completely satisfies customer's request. |
