What does a vehicle module power supply look like?(2)

vehicle module 48V input power supply The distinction between good circuit principles and bad circuit principles can often only be made from a professional perspective. At this stage, power modules can be roughly divided into two types: bare board and potting. The bare board can be based on intuitive methods, such as the layout of electronic components is reasonable, neat, generous, neat, and the solder joints are bright and straight. For encapsulated modules, it is not possible to see the internal conditions, but since the internal conditions are not exposed, it is much better in terms of safety and performance metrics. The soldering process can include hand soldering and wave soldering. The quality of the wave soldering process of mechanized production is better than that of manual soldering.

At the same time, the design of the high-frequency switching transformer winding in the module switching power supply is also very important. The winding of the high-frequency switching transformer not only affects the copper loss, but also relates to the coupling between the high-frequency switching transformer windings, and also affects the iron loss of the high-frequency switching transformer. Influence, the design and manufacture of high-frequency switching transformers have a great impact on the performance of the module switching power supply

The core of the 48V input power supply is the IC, just like the brain of the 48V input power supply, the quality of the IC directly affects various parameters of the 48V input power supply.
