带调光功能的RCC电路分析

摘要

The RCC circuit,which is a self excited flyback converter,has the advantages of simple circuit, low cost and so on,which is commonly used in the small power switch power supply.Nowadays with the rapid development of LED lighting,RCC circuit is also widely used in the design of LED lighting drive power supply.But many LED lighting application requirements LED lamp with dimming function,and ordinary RCC circuit cannot with dimmer compatibility, in this paper,we study how to in RCC circuit added can be compatible with a dimming device of the circuit and the principle were analyzed.%RCC电路即自激式反激变换器,具有电路简单、成本低廉等优点，常用于小功率开关电源中。如今随着LED照明的快速发展，RCC电路也被广泛应用于LED照明的驱动电源设计中。但很多LED照明应用要求LED灯具有可调光的功能，而普通的RCC电路无法与调光器兼容，本文研究如何在RCC电路中加入可与调光器兼容的电路，并对其工作原理进行分析。
