Know how much relevant knowledge! The specific advantages of the power module
In the actual application of the power module, we often find that it does not have quality problems in many cases, but during the installation process, due to the negligence of the installer and other reasons, such as connecting the wrong pin, the input voltage does not meet the specified value, and the load is too large Caused by, etc., so understanding the precautions of the power module in the application is what every practitioner must master.
Early understanding of the benefits of the four major power module attention
Under certain power conditions, the smaller the volume, the better. In the process of packaging, shrinking the volume means expanding the space, so as to provide more space for other parts of the system and ensure the integrity of the function. Under certain power conditions, the smaller the volume, the better. In the process of packaging, shrinking the volume means expanding the space, so as to provide more space for other parts of the system and ensure the integrity of the function. The following small series briefly introduces the benefits of using DC-DC power supply modules
Come take a look! The editor takes you to understand what causes the power module to heat up
High temperature greatly affects the reliability of power modules with high power density. High temperature will cause the life of the electrolytic capacitor to decrease, the insulation characteristics of the transformer enameled wire to deteriorate, the transistor to be damaged, the material to thermally age, and the solder joint to fall. Statistical materials indicate that the reliability of electronic components decreases by 10% every time the temperature of electronic components increases by 2°C. Regarding the thermal planning of the power module, it includes two levels: reducing losses and improving heat dissipation conditions.
Don’t miss it, do you understand these aspects of the power module?
In the circuit system, the importance of power can be called "heart". Therefore, when selecting a power module, in addition to considering the input voltage range, rated power, isolation withstand voltage, efficiency, ripple & noise and other performance characteristics, it is also necessary to conduct reliability tests for its high and low temperature performance and derating design. Circuit input voltage is too low, will make the circuit abnormal. Working for a long time under low input voltage, the life of the circuit will also have a great impact. So from which aspects can you understand the performance of the power module, if you don't know it yet, don't miss it this time, these aspects let you understand the importance of the power module, the editor will briefly introduce it to you!
To introduce you to the main indicators of the power module
Today's society pays more and more attention to energy saving, the lower the efficiency, the better. Especially in some instrumentation industries, in the choice of module power application, the standby power consumption of the module power is very high. The power supply module is generally a power supply that can be directly mounted on a printed circuit board. Due to the many advantages of the module power supply structure, the module power supply is widely used in switching equipment, access equipment, mobile communications, microwave communications and optical transmission, communication fields, such as routers and automobiles Electronic equipment, aerospace. The power supplies produced include switching power supplies, ACDC module power supplies, DCDC module power supplies, military power supplies, and custom-made power supplies. Today, the editor mainly introduces you to several main indicators of the power module, I hope to help and understand you!
