AC-DC power module

module combination
(1) Parallel expansion. Connecting the output terminals of the same module in parallel can enhance the output capability, but the output voltage of the parallel modules should be adjusted to be consistent to ensure relative current sharing and avoid unnecessary oscillations. For modules with large current output, the lead resistance can also be carefully designed to achieve the effect of current sharing. The number of modules connected in parallel in this way should not exceed 2. At the same time, if one of the module outputs is faulty, the entire system will not work properly. The parallel expansion connection circuit RL is the load.

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