The so-called switching power supply, as the name implies, is that there is a door here, once the door is opened, the power will pass, and when the door is closed, the power will stop passing, Switching power supply Some use thyristor, some use switching tube, these two components have similar performance, both rely on the base , (switch tube) control pole (thyristor) is added with pulse signal to complete the turn-on and cut-off, the positive half cycle of the pulse signal arrives, the voltage on the control pole rises, the switch tube or thyristor is turned on, from 220V After rectification and filtering, the output voltage of 300V is turned on, and transmitted to the secondary through the switching transformer, and then the voltage is raised or lowered through the transformation ratio for each circuit to work. So what are the conversion methods of switching power supply? The following is the introduction of Ming Jinfang Xiaobian.


What are the conversion methods of switching power supply?


Switching mode of switching power supply:


1. Converting DC into AC is called DC/AC, often called inverter or inverter power supply, which converts DC of a certain voltage range into stable AC ;


2. Converting alternating current into direct current is called AC/DC, which is to convert alternating current of a certain voltage range into stable direct current;


3. Converting DC into DC is called DC/DC, which is to convert DC in a certain voltage range into stable DC. And of course, there's also a power supply that alternates AC to AC /AC, for example, it is commonly used in aviation and marine fields to convert 220V-50Hz power frequency alternating current into 38V-400Hz intermediate frequency alternating current.


The above conversion methods of switching power supply are shared here. I hope this article will be helpful to you. If there is anything you don't understand, you can leave a message to the editor and we will answer you as soon as possible.
