查询词典 devices

These days, many name-brand electronic devices such as laptops, cell phones, PDAs, and cameras are produced in China. However, this does NOT mean they are cheaper when purchased in the Middle Kingdom. In fact, most name brand electronics are actually more expensive in China than they are in the United States. The only electronics which will be cheaper in China are inexpensive, off-brand, Chinese-made devices such as MP3 players and cell phones.

尽管中国现在是许多名牌电子产品，诸如笔记本电脑，手机，PDA，还有摄影摄像机的生产地，却并不以为着这些东西在发展中国家卖得便宜，相反，大多数名牌电子产品的售价远远高于美国本土，只是那些中国国产的，非名牌的电子产品，像MP3，手机这类的卖的还不算贵。

A novel zero-voltage and zero-current resonant pole soft-switching inverter was proposed to achieve zero- voltage and zero-current switching simultaneously when main power devices turn-on and turn-off. Therefore, turn-on capacitive losses could be reduced for devices which the intrinsic capacitor value cannot be neglected. Additionally losses caused by the tail current can also be reduced, when IGBTs are used as main switches.
