What is the role of the customized non-standard power supply customized module (factory?(3)

The size of the magnetic components is closely related to the switching operating frequency. Within the allowable operating frequency range of the magnetic components, the size of the magnetic components is inversely proportional to the switching operating frequency. To reduce the high-frequency switching transformer and inductance of the module switching power supply The volume of magnetic components and other magnetic components need to increase the switching frequency.

Input protection circuit General vehicle module 48V input power supply supply products use built-in filters, which can meet the requirements of general 48V input power supply applications. If a more demanding power system is required, customized non-standard 48V input power supply customized module (factory 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 48V 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).
