开关电源反激变压器选型设计步骤简介

开关电源广泛应用于电气行业,具有效率高、重量轻、稳压范围宽、安全可靠、功耗小等优点.反激拓扑是开关电源中最简单的隔离拓扑结构,具有元件少、成本低、自动复位等显著特点,而且既可以升压也可以降压,具备其它拓扑结构无法替代的优势,而反激变压器则是此拓扑结构中最为关键的器件.

Design of flyback transformer selection for switching power supply

Switching power supply is widely used in the electrical industry, with high efficiency, light weight, wide voltage range, safe and reliable, low power consumption, etc.. The flyback topology is isolated switching power supply topology in the most simple, has less components, low cost, automatic reset and other notable features, and can also boost buck topology with other irreplaceable advantages, and the flyback transformer is the key device for the most topology.
