4 电路描述
LYTSwitch-4器件是一种将控制器和650 V功率MOSFET集成在一起的器件,用于LED驱动
器应用。LYTSwitch-4可用于单级反激式拓扑结构,提供初级侧调节的恒流隔离输出,
同时使AC输入保持高功率因数。
4.1
输入滤波
保 险 丝 F1 提 供 元件 故 障 保 护。 本 电 路 选 用 了 相 对 较 高的 电 流 额 定 值 ,以 防 止 在 差 模
(1.2 μs / 50 μs)输入浪涌期间出现故障。LYTSwitch-4的快速反应输入过压检测与D2和C6
峰值检测电容一起提供箝位功能,用以限制在IC的MOSFET上出现最大电压应力。可选
MOV(金属氧化物压敏电阻)RV1用来满足>500 V的差模输入电压浪涌要求。RV1的额定
电压为140 VAC,略高于最大指定工作电压132 VAC。二极管桥堆BR1对AC线电压进行整
流,电容C4为初级开关电流提供低阻抗通路(去耦)。
EMI滤波由电感L1以及电容C2、C4和CY1提供。L1和L3上的电阻R2和R24可分别抑制由
滤波元件和AC输入阻抗所产生的任何共振,不然会导致传导EMI测量值增大。
4.2
LYTSwitch-4初级
变压器(T1)一端连接到DC总线,另一端经过阻断二极管D4连接到LinkSwitch-4器件的漏极
(D)引脚。在功率MOSFET的导通时间内,初级绕组中的电流升高,存储的能量随后在功率
MOSFET关断时间内传送到输出。
为向U1提供峰值输入电压信息,经整流AC的输入峰值经由D2对C6充电。然后电流经过
R10,注入U1的电压监测(V)引脚。电阻R9为C6提供放电通路,时间常数远大于经整流AC
的放电时间,以防止V引脚电流被线电压频率所调制(这会降低功率因数)。
输入过压关断功能可使整流后的线电压承受能力(在浪涌和线电压陡升期间)达到内部功
率MOSFET的额定650 BVDSS。
V引脚电流和反馈(FB)引脚电流在内部用来控制LED平均输出电流。对于相位角调光应用,
可在参考(R)引脚(R14)和V引脚上分别使用49.9 kΩ电阻和2 MΩ (R10)电阻,使输入电压和
输出电流保持线性关系。这样可在配合可控硅调光器使用时扩大调光范围。

2013年5月20日
在功率MOSFET的关断时间内,由于漏感的影响,D3、R15和C7将漏极电压箝位到一个安
全水平。在C4上的电压(整流后的输入AC)降到反射输出电压(在设计表格中为参数
VOR)以下时,需要使用二极管D4来防止反向电流流经U1。
二极管D6、C5、C9、R20和R19对U1进行初级偏置供电,能量来自变压器的辅助绕组。
电阻R20提供滤波,以使偏置电压密切跟踪输出电压,从而使输出电流在LED电压发生变
化时保持恒定。电阻R19用于在输出短路条件下对C9放电。
电容C8对U1的旁路(BP)引脚进行局部去耦,该引脚是内部控制器的供电引脚。在启动
期间,C8从与D引脚相连的内部高压电流源被充电至约6 V。充电完成后,U1开始开关,
器件的供电电流再由偏置供电经过R17提供。
建议使用外部偏置供电(通过D5和R17)以实现最低的器件功耗,并在深度调光情况下向
U1提供足够的电源。
电容C8同时用来选择输出功率模式,选择47 μF(低功率模式)可以将器件功耗减至最低,
降低对散热片的要求。
4.3
反馈
偏置绕组电压用来间接地反映输出电压的高低,而无需使用次级侧反馈元件。偏置绕组上
的电压与输出电压成比例(由偏置绕组与次级绕组之间的匝数比决定)的。电阻R18将偏
置电压转换为电流,馈入U1的FB引脚。U1中的内部引擎综合FB引脚电流、V测引脚电流
和内部漏极电流信息,提供恒定的输出电流,同时保持较高的输入功率因数。
4.4
负载断开保护
如果出现开路(断开)负载故障,齐纳二极管VR4将导通晶体管Q2。晶体管Q2然后拉低
FB引脚,强制IC进入自动重启动模式。在软启动结束后,一旦FB引脚电流低于IFB(AR) 阈
值,控制器立即报告摂短路和开路故障。为了降低此故障情况下的功耗,关断/自动重启动
电路将通常以DCAR的自动重启动占空比对电源进行接通(与软启动持续时间相同)和关断
操作,直到故障排除为止。如果故障在自动重启动关断期间消除,电源将保持自动重
启动,直到整个关断时间计时结束。
4.5
输出整流
变压器次级绕组由D7进行整流,由电容C11和C12进行滤波。对于要求采用低纹波的
设计,可提高输出电容值。

DER-350:使用LYT4317E设计的20 W PAR38可调光LED驱动器
可控硅相位调光控制兼容性
对于用低成本的可控硅前沿相控调光器提供输出调光的要求,我们需要在设计时进行全面
权衡。
由于LED照明的功耗非常低,灯具所消耗的电流要小于调光器内可控硅的维持电流。这样会
因为可控硅触发不一致而产生某些不良情况,比如灯具在调光器控制范围结束时关闭和/或
闪烁。由于LED灯的阻抗相对较大,因此在可控硅导通时,浪涌电流会对输入电容进行
充电,产生很严重的振铃。这同样会造成类似的不良情况,因为振铃会使可控硅电流降至零。
要克服这些问题,需要增加有源衰减电路和无源泄放电路。这些电路的缺点是会增大
功耗,进而降低电源的效率。对于非调光应用,可以省略这些元件。
有源衰减电路由元件R6、R28、R29、D10、Q1、Q3、C3、VR5以及R8共同组成。该电
路可以限制可控硅导通时流入输入电容C2和C4并对其充电的浪涌电流,实现方式是在导通
前~0.5ms内将电阻R8串联。在大约0.5 ms后,Q1导通并将电阻R8短路。这样可使R8的功
耗保持在低水平,在限流时可以使用更大的值。电阻R6、R29和电阻C3在可控硅导通后提
供0.5 ms延迟。晶体管Q3在可控硅不导通时对电容C3进行放电,VR5将Q1的栅极电压箝
位在15 V,R28用于防止MOSFET发生振荡。
无源泄放电路由C1和R1构成。这样可以使输入电流始终大于可控硅的维持电流,而驱动器的
输入电流将在每个AC半周期内增大,防止每个导通期间的起始阶段出现可控硅开关振荡。

Place the bobbin item [2] on the mandrel such that pin side on the left side. Winding
direction is the clockwise direction.
Starting at pin 1, wind 31 turns of wire item [4] in two layers. Apply one layer of tape
item [3] between 1st and 2nd layer (spread the winding evenly). Finish at pin 12.
Apply one layer of tape item [3].
Leave about 1” of wire item [6], use small tape to mark as FL1, enter into slot of
secondary side of bobbin, wind 11 turns in one layer. At the last turn exit the same
slot, leave about 1”, and mark as FL2.
Apply one layer of tape item [3].
Starting at pin 10, wind bifilar 8 turns of wire item [5], spreading the wire, and finish
at pin 11.
Apply three layers of tape item [3] for finish wrap.
Cut FL1 and FL2 to 0.75”. Grind core to get 387 μH inductance.
Assemble and secure core halves. Dip impregnate using varnish item [7].

12 调光性能数据
TRIAC dimming results were taken at an input voltage of 120 VAC, 60 Hz line frequency,
room temperature, and a nominal 36 V LED load.
The output current High Limit IOUT (Max) and Low Limit IOUT (Min) were incorporated
based on the USA NEMA publication SSL6-2010 section 4 page 9 for dimming
performance system requirements for reference. The standard however refers to 120
VAC operating input voltage and pertains to the limits as relative light output. The limits
incorporated on the succeeding graphs assumes that 100% relative light output falls on
the maximum operating output current of 550 mA and 0 mA as 0% light output, and input
line of 120 VAC, 60 Hz.

12.2 快速启动(<200 ms) – 采用可控硅调光器
Using a TRIAC-based U.S. dimmer model S-600P-WH (Lutron) with thumb-wheel adjust
set to minimum turn-on (i.e. <30 degrees) which guarantees the LED driver is off when it
is switched to ON position. The test was made by turning/sliding the dimmer knob as
quickly as possible from minimum to maximum position then measuring the time from the
point the dimmer started conducting to the point the output current started rising.
Input voltage: 120 VAC / 60 Hz

13.1 PAR38灯的热测量
The UUT was placed inside a PAR38 with MT-G2 lamp provided by CREE and the
lamp was screwed into a conical metal housing oriented in upside down position
for worse case position. Type-T thermo-couple wire was attached on the body of each
device under test. Temperature readings were recorded when it stabilizes after running
more than one hour with 36 V LED (MT-G2) load at the specified input voltage and load
current. The probe location for the ambient was shown on the figure below.

14.7 输出短路条件下的漏极电压和电流
During output short condition, the IFB current falls below the IFB(AR) threshold and enters
the auto-restart condition. During this condition, to minimize power dissipation on the
power components, the auto-restart circuit turns the power supply on and off at an autorestart duty cycle of typically DCAR for as long as the fault condition persists.

16 输入浪涌
The unit was subjected to ±2500 V 100 kHz ring wave and ±500 V differential surge at
120 VAC using 10 strikes at each condition. A test failure was defined as a nonrecoverable interruption of output requiring supply repair or recycling of input voltage.
The unit tested passed both ±2500 V 100 kHz ring wave and ±500 V differential
surge with and without MOV.
