A 3kW prototype converter is built to verify the effectiveness of the improved converter and the best scheme for the blocking capacitor, and the experimental results are also included in this paper.

本文将改进型零电压全桥变换器应用于高压直流二次电源DC／DC变换器中，研制出一台3kW工程样机，并给出实验结果。

The converter combines the advantages of the PWM technique and soft-switching technique, the PWM is effected all over the whole loads range, and soft-switching is effeted only in the switching transition period, the ZVS of leading-leg is achieved by using the energy stored in leakage inductor of the transformer and the output inductor, the ZCS of lagging-leg is achieved by using a blocking DC capacitor, the ZVS and ZCS are achieved for the whole load ranges (5A~250A).

控制电路采用相移控制方式，综合了PWM控制和软开关技术的优点，在大范围内实现PWM控制，而在功率器件换流期间实现软开关换流，其中超前桥臂利用变压器的漏感，实现了零电压开关，滞后桥臂利用隔直电容，实现了零电流开关，并且整个变换电路能在（5A~250A）的范围内实现软开关工作条件，满足弧焊电源负载变化大的特点。

I switched from the PSU that came with the BN to my STEPS.

我把NOVO的电源切换到了我自己的STEPS。

For this combo, I left the BN running off of the STEPS, and went from there.

对这个组合来说我使用了STEPS电源。

A: This may be a problem with the motherboard, please check the main board of the output voltage is normal, also can try to replace a power supply chassis.

答：这可能是主板出了问题，请检查主板的输出电压是否正常，另外也可以尝试更换一个机箱电源。

Also the boatswain's store, where the forward deck machinery hydraulic power pack is located, was found part flooded with water.

而前甲板机械液压电源机组所在地——甲板部物料间则发现有部分水浸。

The boatswain store where the forward hydraulic machinery power pack is located, had water stain marks on the shell plating, indicating that the space had been port flooded with water.

放置前甲板液压机械电源组的甲板部物料间的壁板上有水渍，表明此处曾部分受水浸。

Absolutely practical, this is my guide book entry of switching power supply and see absolutely right!

详细说明：绝对的实用，这是我开关电源的入门指导书，看看绝对没错！

This book is a book about the power of books.

详细说明：本书是一本关于电源的书籍。

When the BIOS is not the BOOT block destroyed, after the display is not bright, PC speakers have a toot of the alarm sound; If BOOT is damaged, this time after power up, power and hard disk lights, CPU fan switch, but does not start, this when only through programmer to rewrite the BIOS.

当 BIOS 的 BOOT 块没有被破坏时，启动后显示器不亮， PC 喇叭有嘟嘟的报警声；如果 BOOT 被破坏，这时加电后，电源和硬盘灯亮， CPU 风扇转，但是不启动，此时只能通过编程器来重写 BIOS 。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
