SIRIO电感器I系列产品介绍
“电感器”指的是一类广泛的电感元件,具有多种应用和目标,但它们都像“能量罐”。例如,通过考虑高频DC / DC转换器的输出滤波级,输出电感器连续地将电能与输出电容器交换。由于电感器功能包含电流的变化,通过电感器的电流通常主要是具有叠加的高频电流纹波的直流电流(在开关频率或其双倍值,取决于拓扑)。
同样,通过考虑高频转换器的功率因数校正(PFC)级,存在涉及电感器和电容器的高频能量交换;在这种情况下,通过电感的电流主要由电源频率谐波和PFC级工作频率下的叠加电流纹波组成。类似的电感器也用于非隔离的高频转换拓扑结构(降压,升压,降压 - 升压),其中电流波形根据导通模式而变化,即转换器工作在连续或不连续模式。
特征
工业应用通常需要专用电感器,因为每个电感器都需要明确定义的特性。出于这个原因,Sirio选择致力于定制扼流圈开发,自动生产导向,而不是基于标准原材料的电感器目录,通常在我们的wharehouse提供。这种方法可以及时生成具有相同目录产品成本的定制组件。
电感器的主要特征如下。
The term "inductor" refer to a wide category of inductive components, with a big variety of applications and goals, but they all act like “energy tanks”. For example, by considering the output filtering stage of a high frequency DC/DC converter, the output inductor continuously swaps the electrical energy with the output capacitor. As the inductor function is to contain the variation of current, the current through the inductor is normally mainly direct current with a superimposed high frequency current ripple (at the switching frequency, or its double value, depending on the topology).
Similarly, by considering the Power Factor Correction (PFC) stage of a high frequency converter, there is a high frequency energy swap involving the inductor and the capacitor; in that case, the current through the inductor is mainly composed by the mains frequency harmonic and a superimposed current ripple at the working frequency of the PFC stage. Similar inductors are also used in non-isolated high frequency conversion topologies (Buck, Boost, Buck-Boost), in which the current waveforms change depending on the mode of conduction, that is if the converter works in continuous or discontinuous mode.
Features
Industrial applications often require dedicated inductors, as every one needs well defined characteristics. For this reason, Sirio chose to dedicate great efforts to customized choke development, automatic production-oriented, instead of an inductors catalogue, based on standard raw materials, typically available at our wharehouse. This kind of approach makes possible a just in time production of a custom component with the same cost of a catalogue product.
Main features of inductors are the following ones.
