Switching power supply transformer purchase method introduction

Switching power supply transformer purchase method introduction

Switching power transformers are generally used in some high-frequency electrical appliances, the following editorial will introduce you to the switching power transformer should be how to choose, I hope that you through this article for the switching power transformer to choose to be able to have an understanding.

Switching power transformer selection
First, to determine how much power is the power supply.

Second, select the appropriate topology; Third, and then select the power size of the transformer.

Third, and then select the power size of the core and core skeleton.

Fourth, according to the parameters set the primary and secondary turns, wire diameter and so on.
Switching power supply transformer plays the role of energy transfer and conversion. In the flyback circuit, when the switching tube conduction, the transformer converts the electrical energy into magnetic field energy storage. To, when the switch tube cut-off is released. In the forward circuit, when the switch is on, the input voltage is supplied directly to the load and the energy is stored in the energy storage inductor. in the energy storage inductor. When the switching tube cut-off, and then by the energy storage inductor for the continuation of the flow to the load.

The above is about the switching power supply transformer selection details, we understand these steps after the belief that you for switching power supply transformer selection Already have their own decision, I hope you can use the right switching power supply transformer in the right environment.
