What does a 24V power supply look like?(2)

24V Marine boost 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.

(DC/DC) converter
The DC/DC converter converts a fixed DC voltage into a variable DC voltage. This technology is widely used in the stepless speed change and control of trolleybuses, subway trains, and electric vehicles. Responsive performance, and at the same time receive the effect of saving power. Replacing the varistor with a DC chopper can save power by (20~30)%. The DC chopper can not only play the role of voltage regulation (switching power supply), but also can effectively suppress the harmonic current noise on the grid side.

The core of the Marine boost power supply is the IC, just like the brain of the Marine boost power supply, the quality of the IC directly affects various parameters of the Marine boost power supply.
