技术问答

采用power integrations公司的集成LLC功率级IC LCS702HG进行设计的24 V，150 W LLC DC-DC转换器，拥有250 kHz的高工作频率，和满载时大于95％的超高效率，同时，该设计零件数量少，成本低，减少了变压器磁芯尺寸（EEL25）和转换器尺寸，如图1所示。

图1，24 V，150 W LLC DC-DC转换器电路板

图2中是24 V，150 W LLC DC-DC转换器的原理图，采用标称直流输入电压380 V和12 V偏置电源供电，其中高压DC输入将由PFC级提供，12 V来自系统偏置或待机供应，纹波输出电压为240mV，输出电流为6.25A。为了正常工作，该设计必须使用至少10μF的大容量电容，直接放在+380 V输入（B +）和输入回路（0 V）之间，并且直接放在端子上。

初级电路

集成电路U1包含LLC谐振半桥（HB）转换器所需的控制电路，驱动器和输出MOSFET。 U1的HB输出通过阻塞/谐振电容（C11）驱动输出变压器T1，这个电容的额定为工作纹波电流，并且承受在故障条件下的高压。变压器T1的漏电感设计为53μH，这与谐振电容器C11一起，根据图3的等式将初级串联谐振频率设置为大约278 kHz：

图3

其中fr是赫兹的串联谐振频率，Ll是亨利斯的变压器漏电感，Cr是法拉的谐振电容（C11）的值。

通过调节初级匝数来设定变压器匝数比，使得标称输入电压和满载时的工作频率接近但略小于先前描述的谐振频率。实验发现，250 kHz的工作频率是变压器尺寸，输出滤波器电容（启用陶瓷电容器）和效率之间的良好折衷。同时，选择次级绕组匝数以在磁芯和铜损耗之间提供良好的折衷， AWG＃44利兹线用于初级，AWG＃42利兹线用于次级线圈，这种组合在工作频率（大约250 kHz）下提供高效率，选择利兹线的每个规格内的股数作为缠绕配合和铜损失之间的平衡。选择的核心材料是NC-2H（来自Nicera），这种材料产生了可接受的（低损耗）性能，但是选择更适合高频操作的材料，例如PC95（来自TDK），将进一步降低磁芯损耗并提高效率。

元件D1，R6和C8构成自举电路，为U1的内部高边驱动器供电。元件C20，R5和C1提供+12 V输入的滤波和旁路，这是U1的VCC电源，值得注意的是当VCC电压> 15 V时，可能会损坏U1。分压器R1至R4设置U1的高压导通，关断和过压阈值，可以选择分压器值以将LLC导通点设置为360 VDC，将关断点设置为285 VDC，输入过压关断点为473 VDC，内置迟滞将输入欠压关断点设置为280 VDC。电容C9是用于+380 V输入的高频旁路电容，连接U1的D和S1 / S2引脚之间较短的走线。电容器C12与C11形成分流器，用于采样一部分初级电流。电阻R11检测到该电流，结果信号由R12和C7滤波。

电容器C12应根据故障条件下的峰值电压进行评级，并应使用稳定的低损耗电介质，如金属化薄膜，SL陶瓷或NPO / COG陶瓷。该设计中使用的电容器是具有“SL”温度特性的陶瓷盘，常用于CCFL管的驱动器。根据图4公式，所选值将1个周期（快速）电流限制设置为5.5 A，将7个周期（慢速）电流限制设置为3 A：

图4

Icl是以安培为单位的7周期电流限制，R11是以欧姆为单位的限流电阻，C11和C12分别是以纳法为单位的谐振和电流采样电容的值。对于单周期电流限制，在上述等式中用0.9 V代替0.5 V.

电阻R12和电容C7将初级电流信号滤波至IS引脚，电阻R12的最小推荐值设置为220欧， C7的值被设置为1nF以避免由于噪声引起的误跳闸，但是不能高到基本上影响如上所计算的电流限制设定值。这些元件应靠近IS引脚放置，以获得最大效果。 IS引脚可以承受负电流，电流检测不需要复杂的整流方案。电阻R10将死区时间设置为330 ns，U1的最大工作频率设置为773 kHz，U1的FMAX输入由C5过滤。 R10和R19的组合还为U1选择突发模式“1”，这将下突发阈值和上突发阈值频率分别设置为338 kHz和386 kHz。

反馈引脚在反馈引脚中具有2.6 kHz / μA的近似特性，当进入反馈引脚的电流增加时，U1的工作频率也会增加，从而降低输出电压。 R8和R9的串联组合设定U1的最小工作频率，约为115 kHz，该值设置为略低于调节满载和最小大容量电容器电压所需的频率。当反馈环路断开时，电阻R8被C3旁路，以在启动期间提供输出软启动，最初允许更高的电流流入反馈引脚，这导致开关频率开始高然后降低，直到输出电压达到稳压。电阻R9通常设置为与R10相同的值，使软启动时的初始频率等于R10设定的最大开关频率，如果R9的值小于此值，则在施加输入电压时切换之前将导致延迟。光电耦合器U2通过R20驱动U1反馈引脚，限制最大光耦合器电流流入反馈引脚。电容C4对FEEDBACK引脚进行滤波。电阻R21加载光耦输出，迫使其以相对较高的静态电流运行，增加其增益。电阻R20和R21还改善了大信号阶跃响应和突发模式输出纹波，二极管D3将R21与FMAX /软启动网络隔离。

输出整流

变压器T1的输出由D2和C14，C15整流和滤波，这些电容器是X5R电介质，经过精心选择，可用于输出纹波电流额定值。标准Z5U电容器不适用于此应用。输出整流器D2是为高效率而选择的60 V肖特基整流器，交错变压器次级半部（参见第8节中的变压器结构细节）可减少两个半级之间的漏电感，将最坏情况下的PIV降至57 V，允许使用采用60 V肖特基二极管，效率更高。 L1和C16提供额外的输出滤波，电容器C16还抑制由LLC“虚拟”输出系列R-L和陶瓷输出电容器C14和C15引起的~30 kHz的LLC输出阻抗峰值，它还改善了对快速，高幅度负载步骤的响应。电阻R13和R18以及U3参考电压设置电源的输出电压，误差放大器U3通过R14驱动反馈光耦U2。元件C17，C19和R14，R16，R17和R21决定了电源的增益相位特性，选择这些值是为了在标称和极端负载/输入电压组合下提供稳定的操作。当光耦U2的LED没有电流流过时，电阻R15允许所需的最小工作电流流入U3。组件C10和R23是一种软结束网络，用于消除开启时的输出过冲。电阻R23为C23提供人为的高ESR，因此TL431（U3）的输出阻抗主导增益相响应。

变压器规格

变压器绕组方式如图3，其中125 x #44AWG是125股径规格为44AWG的线；6T是绕6圈，其他依此类推即可。

图5 65W高效反激电源的变压器电路图

变压器在每秒60Hz的情况下，其耐压值为交流3000V；当引脚1，5相连，其他所有绕组开路，测量频率为300 kHz和0.4 VRMS时，测得初级电感为350μH；当引脚1，5连接，其他所有绕组开路时，测得谐振频率最小为1400KHz；当引脚1，5连接，引脚FL1，FL2，FL4，FL4短路，测量频率为300 kHz和0.4 VRMS时，测得初级漏电感最大为53μH。
