在过去,集成电路处理大功率是最辣手的问题,所以电源的集成化发展很缓慢。最近由于:①各方面要求节约劳动力的推动,②整个电子设备的小形化要求电源也要小形化,③电子仪器的高级化要求电源高质量等原因,使得电源的集成化也在迅速地研究、引进。一般说来,电源电路从它的作用来看标准化是容易的,而且可以用直流直接耦合回路构成,所以符合集成化的要求。 In the past, integrated circuits to deal with high-power is the hottest problem, so the integration of power development is very slow. The recent due to: ① all aspects of labor-saving requirements to promote the small shape of the entire electronic equipment requires small power, ③ advanced electronic equipment requires high-quality power and other reasons, making the integration of power is also rapidly studying, Introduced. In general, it is easy to standardize the power circuit from its point of view, and it can be constructed with a direct-current direct-coupled loop, so it meets the integration requirements.
