What is the role of the vehicle module power supply?(3)

The distributed power supply mode has the advantages of energy saving, reliability, high efficiency, economy and easy maintenance. It has been gradually adopted by large-scale computers, communication equipment, aerospace, industrial control and other systems, and is also the most ideal power supply method for low-voltage power supply (3.3V) of ultra-high-speed integrated circuits. In high-power occasions, such as electroplating, electrolytic power supply, electric locomotive traction power supply, intermediate frequency induction heating power supply, motor drive power supply and other fields also have broad application prospects.

Input protection circuit General vehicle module 24V input power supply supply products use built-in filters, which can meet the requirements of general 24V input power supply applications. If a more demanding power system is required, vehicle vehicle module 24V input power supply supply the input filter network should be added. Either LC or π can be used but care should be taken to choose a smaller inductance and larger capacitance.

In order to prevent the transient high voltage damage of the vehicle module 24V input power supply supply, it is recommended that the user connect the transient absorption diode to the input terminal, and cooperate with the fuse to ensure that the module is within the safe input voltage range. In order to reduce the common mode noise, Y (Cy) can be increased and several capacitors nf high frequency capacitors are generally selected. R is a fuse, D is a protection diode, and D is a transient absorption diode (P6KE series).
