众人皆知,由于半导体制程的不断精进,数位逻辑晶片的晶体管密度不断增高,运算力不断增强,使运算的取得愈来愈便宜,也愈来愈轻便,运算力便宜的代表是微电脑、个人电脑,而轻便的成功代表则是笔电、智慧型手机、平板。不过,姑且不论摩尔定律(Moors’Law)能否持续下去,有些电子系统的轻便度仍待改进提升,例如笔电出门经常要带着一个厚重占体积的电源配接器(Power Adapter,俗称变压器,但变压器仅是整个配接器中最主要的一个零件),而办公居家用的桌上型监视器(Monitor)也有类似的情形,只是不外带,但依然占体积。
As we all know, due to the continuous improvement of the semiconductor process, digital logic chip transistor density continues to increase, computing power continues to increase, making computing more and more cheap, more and more portable, cheap computing power representatives are micro-computer, personal computer , While the light of the success of the representative is the laptop, smart phone, tablet. However, regardless of Moore’s Law, the lightness of some electronic systems still needs to be improved. For example, a laptop often has a heavy power adapter (commonly known as a transformer) , But the transformer is only one of the main components of the entire adapter), and a similar situation occurs in the monitor for home use, but it is not taken outside, but it still occupies the volume.
