Development On Intellectual Monitor System And Modules Of Communication Switching Power Supply System

The project titled in development on intellectual monitor system and modules of communication switching power supply system, which belongs to upgrade products of our company. In order to make the communication power supply system to be suit to communication apparatus, especially in the centralized maintenance and management, no watch, the new version products are communication switching power supply system with advance, practicality and high reliability. The main research results are summaried as follow:The intellectual controllers of the power supply system have been designed systematically. The micro-controller Rabbit2000 with excellent performance and touch screen technology are adopted to realize the control and management for the power system. The "three-remote" technique has been realized through the upper computer. Utilizing the touch-screen techniques, the various states can be searched and the parameters can be set up.The rectifier modules have been designed. The new technologies are followed in the design of the rectifier modules, such as AFPC, FB-ZVZCS and phase-shift PWM controller etc.The monitor unit of the intellectual rectifier modules has been designed. The single-chip computer is added in the rectifier modules to provide the absolutely protection functions, when the module occurs over-voltage, over-current, over-temperature and under-voltage, meanwhile, the collection and control about the module information become more convenient and the power supply system becomes more reliable.On base of the requirements of switching power supply, a new current-sharing method, intellectual current-sharing techniques, is presented by using the software and hardware each merits.
