摘　　要：本文从LED照明可控硅调光驱动的设计出发(以下“调光”指“可控硅调光”),针对非隔离开关驱动电路,具体探讨影响LED驱动效率的相关因素,并指出开关电路产生关键损耗的功能电路及器件,通过原理分析,提出提高LED驱动效率的相应思路。最后,在满足产品性能和可靠性的前提下,最大限度地提高LED调光驱动的效率。In this paper,starting from the design of LED lighting thyristor modulation drive(the following"dimming"refers to"thyristor dimming"),for the non-isolated switch drive circuit,specifically discuss the relevant factors affecting the efficiency of LED drive,and point out the key loss of the switch circuit function circuit and devices,through the principle analysis,put forward the corresponding ideas to improve the efficiency of LED drive.Finally,under the premise of meeting the product performance and reliability,the efficiency of LED modulation drive is maximized.
