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

vehicle module 24V 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.

Inverter module power supply
High frequency inverter rectifier welding machine power supply is a new type of welding machine power supply with high performance, high efficiency and material saving, which represents the development direction of current welding machine power supply. Due to the commercialization of IGBT large-capacity modules, this power supply has a broader application prospect.
Most of the inverter welding machine power supply adopts the method of AC-DC-AC-DC (AC-DC-AC-DC) conversion. The 50Hz alternating current is converted into direct current by full-bridge rectification, and the PWM high-frequency conversion part composed of IGBT inverts the direct current into a high-frequency

The core of the 24V input power supply is the IC, just like the brain of the 24V input power supply, the quality of the IC directly affects various parameters of the 24V input power supply.
