The application is extremely extensive in the daily life, mainly Be direct current motive, electrolysis, alternator of Li Ci etc. the direct current power supply need. But the outputs electric voltage of the direct current generator be usually unsteady. Use us to need to make it output an electric voltage stability for the sake of the convenience. This system mainly made use of triode transistor and single slice a machine realization to the generator of steady press a control. This text is mainly lay particular emphasis on in the design to the electric circuit part to carry on a description. First, this text will all say the characteristics of direct current generator, basic principle and characteristic of triode transistor, and elaborate that the triode transistor is in the importance in this system. Secondly, this text will relate the basic work principle of the core parts-triode transistor in this system, design request and experiment curve of Jian3 Shu4s triode transistor. Again, this text will elaborate this system in detail the principle of the machine is in the single slice, design process with adjust to try a method. Combine to explain for chart. End, this text describes a synopsis the
