Power supply circuit analysis of pulsed semiconductor laserPulsed semiconductor lasers have the advantages of high peak power and small size, and are widely used in the fields of laser ranging, lidar and free space laser communication.

Selection and use of semiconductor laser power supplyFirst, the basic requirements of semiconductor laser power supply1. Constant current output: short-circuit constant current output, load changes or short-circuit automatic adaptation.2. Output current ripple: ripple, noise and rated output current cannot exceed the maximum current that the laser tube can bear.3. Output voltage ripple: Ripple voltage noise will not damage the laser immediately, but if serious, it will affect the life of the laser.4. Soft start: Slow start current curve, no overshoot.5.

Design and implementation of semiconductor laser power supplyIn order to improve the stability of the optical power output of the semiconductor laser and ensure the safe and reliable operation of the laser, the semiconductor laser power supply can be designed according to the following introduction. The main circuit of driving power adopts synchronous DC/DC mode, which has high output efficiency. The driving circuit can generate 200kHz trigger pulse, which can reduce the ripple of output current and ensure the stability of the output power of the laser.

Design of a low power semiconductor laser driving power supplyWith the semiconductor in communication, measurement and control, medical, integrated optics and other technical fields of wide application, its attention is also increasing, for the design of a high precision, reliable performance, economic, durable driving power has become our current most urgent problem, because of the semiconductor laser "delicate" characteristics, the use of power must be in the performance and quality of strict control. Transfer characteristics of semiconductor lasersAt a certain temperature, wh

Application of semiconductor laser power supplySemiconductor laser market leading fiber laser, gas laser, solid laser market for a while, and several other categories of laser market proportion is similar. However, since 2016, the market share of semiconductor laser has expanded rapidly, with an annual growth rate of 170%. In 2015 and 2015, semiconductor laser accounted for 50% of the total market share of laser. The market share of semiconductor laser power supply also expanded at the same time.

How to install laser engraving machineThe installation of laser engraving machine has the following three steps:1. Installation(1) Insert the control card into the microcomputer PCI slot, tighten the screws, and connect the data cable; Plug in the USB dongle and install the operating software and dongle driver.(2) Connect the laser tube water circulation tube with the anode and cathode conductor, and then put the laser tube clamp ring.

Technical Trends of Switching Power Supply AbroadSince the 1990s, the development of switching power supply has changed with each passing day. Many new fields and new requirements put forward newer and higher challenges to switching power supply. If we observe from the input and output window of a switching power supply, we can find that the input requirements have become more stringent, and products that do not meet the IEC1000-3-2 standard will be gradually eliminated; The output has derived many special application fields, and the difficulty of research and development has become greater.

Switch power output protection policyIn all switching power supply designs, protection against load and protection against power supply due to load failure is a very important aspect to be considered in the design. In the design of military products, a kind of work called failure mode and impact analysis is often required. In this work, each part of the circuit is assumed to be an open circuit fault and then a short circuit fault. In this case, analyze separately how each fault will affect the rest of the circuit.

Various techniques for switching power supplies to reduce lossesThe efficiency of PWM switching power supply without special loss control technology is lower than that of switching power supply with loss control technology. For switching power supplies that have no problem with heat dissipation, such as some off-line power supplies, the efficiency may be satisfactory. But for portable power supplies and devices requiring small size, greater efficiency must be sought.

Classification of switching power suppliesSwitching power supplies can be divided into AC/DC and DC/DC. As a secondary power supply, DC/DC converter has realized modularization, and the design technology and production process have been mature and standardized at home and abroad, and has been recognized by users. However, due to its own characteristics, the primary power AC/DC has encountered more complex technical problems and manufacturing problems in the process of modularization.
