A unified method for fast modelling of dc-dc switching converters in continuous conduction mode (CCM) is proposed in this paper.

本文提出了工作在连续导通情况下DC—DC开关转换器的快速建模的统一方法。

In dc-dc converts, the average dc output voltage must be controlled to equal a desired level, though the input voltage and the output load may fluctuate.

对于直流-直流变流器，虽然输入电压和输出负载会波动，直流输出电压必须控制在一个希望的水平。

In the following example, we replace it with our test domain of "dc=CIFS2k3,dc=in,dc=ibm,dc=com".

在下面的示例中，我们使用 "dc=CIFS2k3,dc=in,dc=ibm,dc=com" 测试域替换它。

To achieve this power savings, rivals need to add external dc-to-dc converters, increasing both the size and cost of their products.
