一、概述开关型电源的广泛应用,进一步丰富了电子变压器的内容,也给电子变压器工作者带来了许多新的问题。开关型电源中的晶体管直流电压变换器是一种效率高、体积小、重量轻、工作稳定可靠的电源变换装置。它是开关型电源的主要组成部份。它的电路类型很多,工作原理也各不相同。但每一种电路都少不了变压器这个器件,可以说变压器是晶体管直流电压变换器的心脏。不同电路中的,或者同一电路不同位置上的变压器,其工作原理和技术 I. Overview Widely used switch-mode power supply, further enrich the content of electronic transformers, but also to electronic transformer workers has brought many new problems. Switching power supply transistor DC voltage converter is a high efficiency, small size, light weight, stable and reliable power conversion device. It is the main part of the switch mode power supply. It has a lot of circuit types and different working principles. However, each circuit are ultimately transformer this device can be said that the transformer is the heart of the transistor DC voltage converter. Different circuits, or transformers on different locations of the same circuit, its working principle and technology
