In this switching power supply, the novel mode of serial two-transistor is adopted to solve the difficulty of choosing switch transistor under the condition of high-voltage input.

该开关电源采用新颖的双管串联模式，解决了高电压输入条件下开关管的选用难题。

This paves the way for new insulating materials which allow the transistor to switch faster, but are not tolerant of high temperatures.

Last year Hewlett-Packard, along with a team of scientists from UCLA, proved the ability to make a switch that could be turned off and on, like a transistor, out of a single organic molecule called a catenane.
