Fault Mechanism and Detection Method of Rectifier Circuit Rectifier circuit is an indispensable part of electronic equipment,its main function is to convert AC power into DC power. However,in the course of use, may also have various faults. This paper will analyze the fault mechanism of the detail, and provide effective detection means. 1.Failure mechanism The fault of the rectifier circuit is mainly related to the rectifier diode, and there are two possible reasons: one is the destructive influence of the external circuit on the rectifier diode; The second is the quality of the rectifier diode itself. The rectifier diode may have two kinds of hard faults, such as open circuit and breakdown, and soft faults such as forward resistance increase and reverse resistance decrease, which will affect the working stability. 2.Key test points The key test point of the rectifier circuit is the output of the rectifier diode. By measuring […]
