Improvement of rectifier diode application in power supply of civil aviation access network 4

By improving the power supply system through the use of diodes, in the event of a malfunction in the FAl6 rectifier power supply or in the UPS power supply A circuit, the rectified power supply system will use the circuit shown in Figure 5 to supply power to the system without power interruption. The main reason is that the FAl6 rectifier module has no negative voltage output, and the anode potential of the diode is higher than the cathode potential (-53.5V) and is conducting forward. Therefore, power is supplied to the FAl6 equipment from the DC distribution cabinet at this time.diode

4 Conclusion

In terms of component selection, the author chose a 2CZ type silicon rectifier tube with a rated current of 30A and a reverse withstand voltage of 1200 V. This diode does not require a heat sink at room temperature. Moreover, this power supply solution is simple and easy to implement, with minimal investment, and does not require targeted daily maintenance. We hope it can provide some help to other peers' power supply improvement plans.diode
