VMOSFET have mary advantages over bipolar transistors, they are very effective, especially in power electronics applications, A compact laser power supply with good performances has been developed by using devices of VMOS, opto-isolator etc. VMOS场效应晶体管有许多超过双极晶体管的优点,特别适合于功率电子学应用。我们使用VMOS管、光隔离器等器件研制的小型激光器电源,性能良好。
By taking Al/ Alq 3/ TPD/ ITO/ glass organic/ polymer light emitting diode ( OLED) as a light emitter and a integrated photo-detector formed by photo-diode and bipolar transistor as a photo-receiver, a novel opto-isolator has been constructed which is investigated experimentally. 对以Al/Alq3/TPD/ITO/玻璃结构的有机/聚合物发光二极管(OLED)为发光器件,以光电二极管和双极晶体管构成的复合光探测器为光接收器件组成的光耦合器进行了实验研究。
