Design Of The Ethernet-based Controll Intelligent Switch Power Supply

With the switch power technology development and application, the electric powerfine conversion has become reality, Ethernet control intelligent switch power technologyhas become indispensable to many areas of the basic equipment. In the 21st digitalinformation century, the requirements of Ethernet control intelligent switch power supplyare improved. From the network control switch power supply’s voltage and currentstability, to ripple coefficient, power size, efficiency, response time and so on, in people’sefforts to seek the best design theory and technology of the network control intelligentswitch power.This article through analysis and research in the traditional RCC switching powersupply circuit, expounds the network control technology of the intelligent switch power athome and abroad. The control power components and micro controller is the foundationof intelligent switch power supply, and the Ethernet-based control is the foundation ofswitch power supply network. This article design the based on the network control switchpower control module and the ARM7 micro controller LPC2132 control PWM module ofRCC switching power supply circuit. Network control module is designed for adjustingswitch power parameters and controlling system. Through the network control module,the system can connect the ARM, and they can form of a digital control system of switchpower parameter acquisition, adjustment and control, this system can be used for controlswitch power operation conveniently. Network control module mainly using single chipexchange controller RTL8019AS to achieve. Intelligent switch power supply generalcomposition of pulse width modulation (PWM) control IC and transistor. This articlemakes the switch power supply circuit output voltage, current and output state can adjust,and improve the output voltage stability and response time. Through the softwareprogramming, may to cause the system further upgrade, to facilitate users according totheir needs, and also to choose the different control functions flexibility.
