The combination of modules (1)Parallel expansion.
Parallel the outputs of the same modules can enhance the output capability, but the output voltages of the parallel modules should be adjusted to ensure relative current uniformity and avoid unnecessary oscillation.
For modules with large current output, lead resistance can also be carefully designed to achieve current sharing effect.
The number of modules connected in parallel by this method should not exceed 2.
At the same time, if one of the module outputs is faulty, the whole system will not work properly. The parallel expansion connection circuit RL is the load. (2)Redundant hot backup in parallel.
Parallel connection of the same module output through diodes can enhance the output capability to improve the reliability of the power supply system.
In principle, if the corresponding output alarm circuit is matched, the module is placed on the detachable bus, so that the faulty module can be replaced in time.
There is no quantity limit for modules connected in parallel by this method. D is generally a Schottky diode. (3)Series expansion.
Connecting the output terminals of the same module in series can multiply the output voltage and increase the power accordingly, while the output terminals in series must be connected with diodes for protection. Dear Customer: Hello!
