What is the reason that the power module is difficult to start? Because the module power supply has isolation function, strong anti-interference ability, with its own protection function, it is easy to integrate.
The modular design of power supply module shortens the design and development cycle of the product to a great extent, and it is very simple to use. If the power module is not used properly, it will be difficult to start. There are two main reasons why the power module can not start normally. One is that the output load is too large, the other is that the input energy is insufficient.
First of all, in the case of less destructive, the power module is difficult to start, or even unable to start. In the process of using the power module, you can see that the output voltage of the power module is normal. There is no output at the output and the power module is not damaged. And why?
The external capacitance is too large; The capacitive load is too large; The load current is too large; The input power is insufficient.
To solve this problem, by adjusting the output and load capacitance or input power, the external capacitance can be improved, so it is difficult to start the power module for a long time, so it is necessary to select the appropriate capacitance load.
When the capacitance load is too large, the appropriate inductor can be connected first. If the output load is too heavy, extend the start-up time and select the appropriate load. Switch to a more powerful input power supply
