A good power adapter, from development and design to factory use, not only must consider the aesthetics of the appearance, but also consider the rationality of the structure of the switching power adapter. During work, it is necessary to strictly monitor the temperature rise range value, so as to avoid excessive temperature, resulting in a decrease in the efficiency of the switching power supply adapter. In the process of using the switching power adapter, the temperature of the power supply is too high, which is mainly caused by two aspects, one is the MOS tube, and the second is the design problem of the power adapter itself. Today, let’s learn about how to solve the problem of excessively high temperature of the switching power supply adapter.  

First of all, from the perspective of MOS transistors, the general switching process loss is caused by the size of a single charge and the switching time. We can use faster and shorter recovery time electronic components to reduce the working process of the switching power supply adapter. Among the losses.  

As for the problem of on-state loss, we can use switches with low on-state resistance to reduce the loss. Of course, better design can also reduce loss, which depends on the level of designers and engineers. In the design process of the adapter, the MOS tube heats up the most, because its loss is also the most serious, and the MOS tube loss mainly has two points, one is the on-state loss, and the other is the switching process loss.

Dajing Power adopts intelligent identification, multiple protections, and provides nine-fold circuit security protection, and the charging process is worry-free. The intelligent control chip and charging and discharging chip are used to not only protect the power supply itself, but also protect it according to the connected equipment. The chip comes with overvoltage, overload protection, and complete protection functions. Only a high-quality power chip can make it have a longer life. Dual MOS power devices, using the principle of resonance, make the loss smaller and higher efficiency, and the MOS tube with sufficient power guarantees the maximum peak value. Dajing Power has focused on power supply manufacturing for 18 years, independent power supply research and development, and tailor-made exclusive power solutions for you.  
 

What is the difference between a waterproof transformer and a rainproof transformer?
What is the difference between a waterproof transformer and a rainproof transformer?
When many people don’t know about waterproof transformers and rainproof transformers,May mistakenly think that the two are the same。In fact, no matter from the waterproof level or from the performance and application,The two are different。 1. The difference in protection level: Waterproof transformer waterproof grade up to IP67-IP68,Can completely prevent dust from entering,And it can be soaked in water for a long time。 The waterproof rating of the rainproof transformer is IP44,It can only prevent solid objects larger than 1mm from entering (dustproof),The liquid splashed into the shell from any direction has no harm effect (rainproof)。 2. Different applications: Waterproof transformers are generally used in lighting decorations,For example, in underwater lights, underground lights, fountain lights and some large outdoor lighting projects。 Rainproof transformers are generally suitable for building lighting, night lighting, guardrail tubes, digital tubes and other lighting projects,Optimal matching power supply for outdoor products。 Dongguan Rico Electronic Co., Ltd. was established in October 2011.
