Abstract

With the rapid development of modern communication technology, higher requirements h

ave been put forward, communication power supply reliability, weight, volume, efficiency etc.. The phase shift and the application in high power DC / DC voltage and current structure of full bridge converter is simple, high output power, high efficiency, easy to realize soft switching, has a series of advantages by the power switch, such as small capacity, it is very important to research on it. First of all, the current DC / DC converter trigger circuit, input circuit, feedback control circuit, push-pull transformer in detail, loss of focus of MOS field effect transistor research and analysis. Secondl. Secondly, the paper simply introduces the parameters required in the use of the experimental equipment, established the model for stability, Protel Altium Designer 6.9 simulation software system is analyzed in the paper. Finally the simulation results. Finally the simulation results, according to the actual circuit of their own, so that all the normal debugging, achieves the expected effect.

Keywords: 砂浆机DC/DC boost 化学膨胀螺栓converter; push-pull transformer; feedback circuit control chip
