【选型】Central LED驱动器PFC电路的元器件选型推荐方案,助力其功率因数校正
随着LED驱动器的广泛应用,以及人们对于能源利用率的日益重视,LED驱动器的功率因数已经成为衡量驱动器经济可行度的重要因素之一。功率因数是指LED驱动器的有效功率和总功率的比值,代表着电力的有效利用率,该因数越高,表明LED驱动器的电力利用率越高,可以有效提高驱动器的经济性。而能够调整功率因数的电路模块称之为功率因数校正(PFC)电路。
作为电子设备的内部模块,PFC必须依靠电子元器件来实现功率因数校正这一功能。而为了能够保证长期稳定可靠的PFC电路功能,Central推出了性能优异、坚固耐用的电子元器件,解决方案如图2所示,类型和型号分别为肖特基二极管/整流器(CMLSH05-4/CMLSH1-40/CMSH2-60/CMSH2-100/CMSH3-60)和超快恢复整流器(CMR3S-04/CMR3U-04),电气参数如表1~表2所示。
