【Abstract】 There are some intensive interference in the welding controlled system based on 32 bit MPU AT91RM9200,so it is greatly important for the design of the System Power Source.Introduce in brief the principle of the System Power Source and the selection of the relative instruments,then the most important is to explain the design of the Power Source electrocircuit and to enhance the particular measure of the anti-interference ability.This electrocircuit has higher reliability and electromagnetic compability than others,and it can fulfil the designed request for the system running steadily.更多还原
