【应用】使用DPA424G DC-DC开关转换IC设计的24.5W负压转换电源,功率转换效率高达92%
系统基本介绍
本文描述了Power Integrations生产的DPA-Switch系列下DPA424G DC-DC开关转换IC在PABX电话系统的线路卡上使用的电源原型,该电源使用基于晶体管的非隔离反馈而不是光耦合器,避免了某些电信电源不允许使用光耦合器的问题;输入-40V的直流电压,即可输出24.5W的稳定功率;内置输入欠压锁定,当输入电压低于某一值时,电源芯片停止工作并进入保护状态;支持单转换器,用于产生双输出电压;功率转换效率极高,满载时高达92%;同时,由于元件数量少,结构设计紧凑,故降低了生产成本。其电路板如图1。

电路设计详解
DPA424G DC-DC开关转换IC设计的24.5W电源采用非隔离反激式配置,DPA-Switch(U4)为此反激电源提供PWM,控制器以及主开关MOSFET;输入电源通过电容(C16)去耦滤波,用于滤除高频噪声;电阻R5编程DPA-Switch(U4)的欠压关断功能,将在32.9 V(最小值)和38.7 V(最大值)之间的电压下进行启动;电阻R14编程DPA-Switch进行电流限制;电容器C13和C14提供器件去耦,C14还可以对器件的启动和自动重启周期进行编程;电阻R13与C14一起提供反馈补偿;元件D2,C1,R1,R2和R3形成RCD钳位电路,以限制初级关断时的漏电感电压尖峰;变压器T2的电感提供电路的能量存储和转换部件; 因为-28V输出的绕组连接到0V输入轨,因此是非隔离的,但变压器确实为产生-65V直流输出的绕组提供了功能隔离(非安全隔离),产生了-40 V 直流输入轨道;通过二极管D1和电容C11,C17和C18整流和滤波输出-28V,通过二极管D4和电容C9和C20整流和滤波输-65V。
在此电源中,输入轨用作产生输出电压的参考电压,因此我们需要确保0 V和-40 V电源轨上没有初级侧开关纹波,这是使用额外的去耦电容C19和C15实现的,如果没有这两个电容,初级开关产生的所有纹波也会叠加在输出电压上;电阻R8检测-65 V输出电压,元件R11,Q3和R19组成一个反相跟随器,以提供-28 V输出电压的感应,将这两个感测信号相加并在电阻器R15上产生电压,电阻器R15控制LM431(U3);元件R12和C12为U3提供补偿,以确保其频率响应仅限于低频信号,电阻R20为U3提供偏置电流(来自-40 V电压轨),元件R18,Q2,R16提供电平转换以传输反馈信号;电容器C21增加了环路的高频响应,元件R17和Q1提供与U4的CONTROL引脚的最终连接,在启动时发生时,若基极低于控制引脚电位,则二极管D5防止Q1的集电极 - 基极结发生反向偏置;电阻R17与R16,R18配合使用,可对环路的直流增益进行编程。该电路的原理图如下图2。

变压器规格
变压器绕组方式如图3,其中W4的2 X 31 AWG的2是两股线,AWG是线径规格;8T是绕8圈,W1,W2,W3依此类推即可。
图3 - 变压器电气图
当引脚1,2连接,其他所有绕组开路,在测量频率为400 kHz和0.4 VRMS的情况下,测得初级电感为57μH;当引脚1,2连接,且其他所有绕组开路时,测得谐振频率最小为5 MHz;当引脚1,2连接,引脚5,6,7,8短路,在测量频率为400 kHz和0.4 VRMS的情况下,测得初级漏电感最大为500 nH。
实际效率
经过实际验证,该电路的电源可以稳定输出24.5W,功率转换效率极高(满载时高达92%),具体情况如下图3。

注1:以上数据采用-65V和-28V的各种负载组合负载。
因此,用DPA424G DC-DC开关转换IC设计的24.5W电源可以用于需要提供负压的芯片所设计的电路中,该电路设计在消费电子部件,大家电,工业自动化,工业伺服,工业设备控制,小家电,室内照明,智能家居等行业和领域都有广泛的应用。
