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

(2) Parallel connection of redundant hot backup. Connecting the output terminals of the same module through diodes in parallel can enhance the output capability and improve the reliability of the power supply system. In principle, if it cooperates with the corresponding output alarm circuit, put the module on the busbar that can be removed, so that the faulty module can be replaced in time. There is no limit to the number of modules connected in parallel in this way. D is generally a Schottky diode.
(3) Series expansion. Connecting the output terminals of the same module in series can double the output voltage and increase the power accordingly, and the series output terminals must be connected with diodes for protection.

Input protection circuit General dc switching Marine boost voltage power supply supply products use built-in filters, which can meet the requirements of general Marine boost voltage power supply applications. If a more demanding power system is required, switching Marine boost voltage power supply module 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 dc switching Marine boost voltage 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).
