- W4328090478 abstract "The traditional laser power supply is built and become of analog circuit, and the precision requirements of circuit design and automatic control are difficult to meet the aerospace level. Therefore, it becomes particularly important to realize the all-digital design of spaceborne laser power supply. On the basis of FPGA technology, we design a kind of Ethernet protocol, 422 level transmission form to realize the communication with the management controller, and provide laser timing signal, Q-switched signal, AD/DA control signal for the laser. In this way, the transmitter timing and parameter adjustment functions such as charging current, charging high voltage, LD discharge current, LD drive timing sequence, Q-switching drive high voltage and Q-switching drive timing sequence which required by the laser can be realized. In addition, when the charging high voltage, charging current and LD discharge current exceed the threshold, the transmitter can be turned off automatically to realize the automatic protection function. The test results show that the design of all digital spaceborne laser power supply meets the functional requirements." @default.
