“…If the SOFTREF terminal voltage is higher than 4 V at this time, 𝑄 is turned off; if the SOFTREF terminal voltage is lower than 4 V at this time, 𝑄 is turned on. The SOFTREF is charged by the branch where 𝑄 and 𝑄 are located, the voltage of SOFTREF increases, and the collector voltage of 𝑄 also increases [17]. When the SOFTREF terminal voltage is charged to about 4 V, 𝑄 enters the saturation region.…”

The basic idea of the circuit fault diagnosis method based on fault logic is to establish a computer expert database system first, connect the computer to the GPIB interface card, and then connect each intelligent instrument through the GPIB standard bus. Through the connection of the tested object adapter and the tested object, a circuit fault expert diagnosis and test platform are formed. Based on the traditional fault simulation model, this paper improves the fault logic circuit of switching power supply, designs the system model of fault simulation, deals with the logic structure and circuit hierarchy respectively, and produces the final output through the logic gate circuit by comparing the results of the fault logic circuit and the fault-free logic circuit. The designed switching power supply fault logic circuit works in the switching state, which has the characteristics of low loss and high energy conversion efficiency. Through the simulation analysis, the output is connected to the comparator, which plays the role of the whole wave. The simulation results are in line with the parameter indicators. The functional test results of the chip show that the function of the module is basically normal, which has practical application value and good portability and can be used as a reference for similar electrical designs.

The output power and wavelength of semiconductor lasers are mainly affected by operating temperature. In order to improve the stability of Laser Diode (LD), a temperature control system is designed in this paper. This system adopts an advanced Particle Swarm Optimization (PSO) algorithm to resolve real-time Proportional-Integral-Derivative (PID) parameters for different input, which is implemented on field-programmable gate arrays (FPGA) with excellent parallel performance. Experimental results show that the LD can stabilize with temperature stability of 0.20% within 1 hour of operation, output optical power stability of 0.05%, and the deviation of optical wavelength 0.03𝑛𝑚.
