【应用】反向恢复时间45ns的快恢复二极管降低PFC电路损耗,正向压降低至1.4V,使用寿命更长
PFC(功率因素校正)电路一般在75W及以上的开关电源上应用,功率因数可以衡量电力被有效利用的程度,当功率因数值越大,代表其电力利用率越高,在开关电源上增加PFC电路可提高电力的利用率。
图1 PFC boost电路
如图1,在PFC电路工作时,开关管不断地以一定的开关频率在进行开关动作,在这个过程中二极管也不在不断切换导通与截止的状态,实际上理想二极管并不存在,二极管的状态切换存在一个反向恢复时间,在这个时间内,二极管会通过很大的电流,增加损耗。为了尽可能减少损耗,可选用SMC的快恢复二极管SDUR6030W,优势如下:
1、 反向恢复时间低至45ns,可减少损耗;
2、 平均整流正向电流可达60A,可应用在大功率电路上;
3、 正向压降低至1.4V@25℃,功耗更小,使用寿命更长;
4、 封装采用TO-247AC的两脚封装,易于设计,占用PCB面积小。

介绍快恢复二极管的导电特性及关键参数
快恢复二极管是一种专为高频和高速开关电路设计的半导体器件。它具有快速的恢复特性,能够在导通和截止状态之间迅速切换,因此在电源转换、电机驱动和功率因数校正(PFC)等领域得到了广泛应用。理解其导电特性及关键参数,不仅有助于优化电路设计,还能提高系统的整体效率和可靠性。

【选型】空调PFC推荐国产600V/30A的快恢复二极管MUR3060P,Trr仅35ns
考虑到PFC升压电路中电感电流是连续的,会在续流二极管上产生很大的反向恢复损耗,不利于高效电源设计需求,故而续流二极管通常采用快恢复二极管以降低反向恢复损耗;因续流二极管正向导通损耗无法避免,尽量选择正向压降VF更低的二极管。因此本文推荐国产扬杰科技的快恢复二极管MUR3060P。

ROHM(罗姆) SiC(碳化硅)肖特基二极管选型指南(中文)
描述- SiC肖特基势垒二极管(SiC SBD)具有很小的总电荷(Qc),低开关损耗且高速开关工作。因此,它被广泛用于电源的PFC电路中。此外,与硅基快恢复二极管的trr(反向恢复时间)会随温度的升高而增加不同,碳化硅(SiC)器件可保持恒定的特性,从而改善了电路性能。制造商能够减小工业设备和消费类电子产品的尺寸,非常适合在功率因数校正电路和逆变器中使用。
