反激电路中的输出电容如何选择?
开关电源的输出都有电容,大部分使用的是电解电容,电解电容的选择一般是根据其耐压,纹波电流,纹波电压等来选择的,但是容值的大小现在大部分都是根据经验值去选择,这篇文章就会教大家来分析反激电路DCM模式的电解电容如何选择。
一开始要知道电解电容的耐压值是如何选择的,其实电解电容的电压的选择是非常简单的,一般是根据输出的电压,然后再要考虑过压的电压值,耐压值一般比输出过压值要高1.2倍。
容值的选择最主要的是要根据纹波电压的值,我们知道,电容的充放电的过程都会有纹波电压的产生,除此之外电解电容也不是一个理想的电容,它有ESR,ESL等串联在电解电容上,高频的纹波电流会产生纹波电压,这个纹波电压还不小,所以实际计算的时候是需要考虑的。
电解电容的寿命不仅仅是跟电容的温度有关,有效值纹波电流也会有相应的影响。接下来,通过ICW3783B-12V1A的反激电路进行详细讲解,如图2所示。
首先,熟悉一下ICW3783B产品。ICW3783B是合肥艾创微电子科技有限公司最新一代的恒压、恒流控制芯片,优化了动态响应和驱动等性能,能做更大的输出功率。芯片内置了Vcво为850V的功率三极管,适用于充电器和适配器。
ICW3783B采用特有的输出线损补偿技术,可以有效的补偿输出电流在输出线上的损耗压降。
ICW3783B具有多重保护功能,包括开路保护,过压保护,短路保护、过温保护等功能。
ICW3783B采用SOP-7封装,其内部框图如图1所示。
图 1
根据图2的ICW3783B应用原理图,首先要分析电解电容上面的几个电流,IL是后级电路二极管导通后的电流,Io是输出负载的电流,lc的是电容上面的电流,同时电容是有充电电流Ic和放电电流-Ic,对于一个稳定的电源,电解电容上面的充电电流与放电电流应该是相等的,如果充电电流大于放电电流,输出电压肯定会升高,要是充电电流小于放电电流的,输出电压会下降。
图 2
那么,具体的看图3的波形,图3中的Isp是副边变压器的最大电流,是原边最大电流Ip通过匝比折算来的,Isp=n*lp,n是原边与副边的匝比,on为原边导通时期,off是原边关断时期。
图 3
从图3的波形可以看出:
1、当原边导通的时候,输出的电流Io都是由电解电容提供。
2、当原边关断的时候,绕组上面的电流导通值Isp大于输出电流Io,这个时候输出的电流是由变压器后级二极管导通后的电流IL提供,同时电解电容上面也正在充电。
3、当后级二极管导通后的电流IL小于输出电流Io的时候,输出的电流Io一部分是后级二极管导通后的电流IL提供,一部分是电解电容的放电电流-Ic提供。
电容的充电与放电是因为电容的电压有变化,充电的时候一般是从电容低电压开始,当变压器绕组电流等于输出电流的时候,电容的纹波电压是最大值,然后开始放电,一直放电到二极管导通为止,这个时候的电容纹波电压是最低的。
那么,电容的充放电引起的纹波电流的参数是如何计算的?其实充电的整个过程就是电容上面的纹波电压由最低到最高的过程,所以只要知道充电时间就可以求出纹波电压了。
首先需要求出给电容充电的时间,也就是二极管的电流大于输出电流的整个时间,那么根据实际电感电压公式 V=L*di/dt,di=lsp-lo,dt就是二极管电流大于输出电流的时间段Tc,Tc如公式1计算所得。
Tc=L*(lsp-lo)/Vo (公式1)
因为在整个充电时间里面,电感电流是线性下降的,所以整个充电时间里面的平均电流为Ic,Ic如公式2计算所得。
Ic=(lsp-lo)/2 (公式2)
再根据电容的充电公式3所得,其中V就是充电引起的纹波电压。
C*V=Tc*Ic (公式3)
根据以上三个公式,就可以得出电容的容值C,C如公式4计算所得。
C=[Ls*(lsp-lo)^2]/(2Vo*Vrip) (公式4)
最后说明,以上公式计算出的容值为理论值,因大多数输出电容都使用电解电容,电解电容是有ESR的,所以实际取值要比计算值大的多。
在实际的电解电容取纹波电压值时,是要根据ESR的大小与纹波电流的大小来计算,通过流过电容的峰值电流乘ESR,小于要求的纹波电压就可以了,计算如公式5所示,然后根据ESR找合适的电解电容。
Vrip=lsp*ESR (公式5)
