PARKER派克气缸GDC50-300 3/8例如个人电脑，而开关电源就进行两者之间电压及电流的转换。开关电源不同于线性电源，开关电源利用的切换晶体管多半是在全开模式（饱和区）及全闭模式（截止区）之间切换，这两个模式都有低耗散的特点，切换之间的转换会有较高的耗散，但时间很短，因此比较节省能源，产生废热较少。理想上，开关电源本身是不会消耗电能的。电压稳压是透过调整晶体管导通及断路的时间来达到。相反的，线性电源在产生输出电压的过程中，晶体管工作在放大区，本身也会消耗电能。开关电源的高转换效率是其一大优点，而且因为开关电源工作频率高，可以使用小尺寸、轻重量的变压器，因此开关电源也会比线性电源的尺寸要小，重量也会比较轻。若电源的高效率、体积及重量是考虑重点时。

PARKER派克电磁阀PHS530E-03-24V-FL 3/8显然不可取。为此，人们往往需要配备限制电机起动电流的起动设备，过去人们多采用Y/△转换，自藕降压，磁控降压等方式来实现。这些方法虽然可以起到一定的限流作用，但没有从根本上解决问题。伴随传动控制对自动化要求的不断提高，采用可控硅为主要器件、单片机为控制核心的智能型电动机起动设备－软起动器，已在各行各业得到越来越多的应用，由于软起动器性能优良、体积小、重量轻，并且具有智能控制及多种保护功能，而且各项起动参数可根据不同负载进行调整，其负载适应性很强。因此电子式软起动器将逐步取代落后的Y/Δ、自耦减压和磁控式等传统的减压起动设备成为必然。电力电子技术的快速发展，智能型软起动器得到广泛应用。智能型软起动器是一种集软起动、软停车、轻载节能和多功能保护于一体的新颖电机控制装置。

总之，只有了解用户、了解任务才能设计出好的人机界面。确定为完成此系统功能人和计算机应分别完成的任务任务分析有两种途径。一种是从实际出发，通过对原有处于手工或半手工状态下的应用系统的剖析，将其映射为在人机界面上执行的一组类似的任务；另一种是通过研究系统的需求规格说明，导出一组与用户模型和系统假想相协调的用户任务。逐步求精和面向对象分析等技术同样适用于任务分析。逐步求精技术可把任务不断划分为子任务，直至对每个任务的要求都十分清楚；而采用面向对象分析技术可识别出与应用有关的所有客观的对象以及与对象关联的动作。考虑界面设计中的典型问题设计任何一个机界面，一般必须考虑系统响应时间、用户求助机制、错误信息处理和命令方式四个方面。
