【应用】基于隔离型LED驱动器LYTSwitch-6的35W隔离反激填充PFC电源电路
Power Integrations公司推出LYTSwitch™-6系列安全隔离型LED驱动器IC,可提供65 W无闪烁输出,效率可高达94%,并且待机功率低至15 mW,同时提供支持两级或单级PFC的配置选项。本文介绍了一个恒定电压(CV)输出35 W隔离反激式电源,带有用于LED照明应用的单级功率因数校正电路。电源设计为在0 A至2.92 A输出电流负载范围内提供12 V恒定电压。它还能够为LED照明应用提供2.98 A恒定电流输出。该电路板经过优化,可在140 VAC至320 VAC的输入电压范围内工作。
LYTSwitch-6 IC在单面安装的离线反激式开关IC中集成了初级,次级和反馈电路。它包含主FET,初级侧控制器和次级侧同步整流控制器。该器件还包括一项创新的新技术FluxLink™,可安全地桥接隔离栅,无需光耦合器。

添加了开关填谷PFC电路,以满足照明应用中的高PF要求。存储在PFC电感上的能量通过直接能量传递传递到负载,从而降低功率损耗。
DER-637采用LYTSwitch-6 IC,可在整个输入范围内提供精确,快速的瞬间响应,恒定电压和高功率因数。关键的设计目标是在整个输入电压范围内实现高效率和高功率因数。
电路描述
LYTSwitch-6器件(LYT6068C)在单个inSOP-24D封装中集成了初级MOSFET,初级侧控制器和次级侧同步整流控制器。该IC还包括一项创新的新技术FluxLink™,可安全地桥接隔离栅,无需光耦合器。LYTSwitch-6 IC配置为驱动35 W反激式电源,带有开关填谷PFC电路,在140 VAC至320 VAC的输入范围内提供高功率因数12 V恒压电源。

输入EMI滤波器和整流器
输入保险丝F1提供安全保护,防止组件故障。压敏电阻RV1用作电压钳,可在线路瞬态电压喷涌发生期间限制初级线圈上的电压尖峰。选择350 V额定部件,略高于最大规定工作输入电压(320 V)。交流输入电压由BR1全波整流,以实现良好的功率因数和低THD。
LYTSwitch-6初级侧控制
隔离反激式电源由LYTSwitch-6 IC LYT6068C控制。变压器(T1)初级的一侧连接到大容量电容器(C4)的正输出端,而另一侧连接到LYTSwitch-6 IC(U1)内部的集成650 V功率MOSFET的漏极。由D4,R2,R15,C7,R3和VR1组成的低成本RCDZ缓冲钳限制了由于变压器漏感的影响导致的峰值漏极电压尖峰。
LYTSwitch-6二次侧控制
LYTSwitch-6 IC的次级侧控制提供输出电压和输出电流检测。次级变压器由同步整流MOSFET(Q1)整流,由LYTSwitch-6 IC的同步整流器驱动(SR)引脚驱动。然后通过输出电容器C10和C16对其进行滤波。在SR FET上增加RC缓冲器(R7和C9)可降低漏极 - 源极之间的电压应力。与变压器次级绕组串联的LC滤波器(L3和C17)有助于进一步降低SR FET漏极 - 源极之间的电压尖峰,如果简单的RC缓冲器不够,几乎不会影响系统效率。元件L3是单匝铁氧体磁珠,与并联陶瓷电容器C17配合使用。
PFC电路操作
如果没有增加PFC电路,反激式电源的功率因数通常在满载条件下约为0.5至0.6。反激式电源电路的输入通常包括全波桥式整流器(BR1),后面是一个存储大容量电容器(C4),能够保持大约等于输入正弦波峰值电压的电压,直到下一个峰值达到为电容器充电。输入充电脉冲电流必须足够高以维持负载直到下一个峰值。这意味着充电脉冲电流比平均电流高5-10倍,与电压波形具有高相位角差; 因此,来自该标准配置的预期PF低而THD高。
