There are three control principles for switching power supplies
Sep 18, 2018


      The first type is a mode in which the pulse width adjustment end switch period is constant, and the air ratio is changed by changing the pulse width;

      The second type is the pulse frequency adjustment, the conduction pulse width is constant, and the duty ratio is changed by changing the frequency of the switching operation;

      The third is the way in which the mixing adjustment on-pulse width and the switching operating frequency are not fixed and can be changed from each other. It is a mixture of the above two modes.

      There are many working methods of switching power supply. This is part of it. The working principle of switching power supply is not the same. But through this part you can know the other parts of the switching power supply. Because the working principle and design principle of the switching power supply are similar. So through this working principle, you can know the other working principle of the switching power supply.
