运行开关电源的方法和开关电源
摘要：
本发明涉及一种开关电源，它具有变压器(1)，该变压器包括至少一个初级绕组，该绕组可以通过开关元件(4)连接在直流电压上，该变压器还包括至少一个次级绕组，它可以通过包括至少一个二极管(2)的整流器电路连接在负载上，其中所述开关电源包括至少一个压电风扇(8)，它在变压器(1)和/或开关元件(4)和/或二极管(2)上引起气流。产生的气流可以有目的地偏转到要被冷却的组件上，其中使气流量总体上保持较小，由此不会由于空气颗粒引起脏污。
摘要（英）：

The invention relates to a switched mode power supply with a transformer (1), which comprises at least one primary winding, which can be connected to a DC voltage via a switching element (4) and whichThe invention relates to a switched mode power supply with a transformer (1), which comprises at least one primary winding, which can be connected to a DC voltage via a switching element (4) and whichcomprises at least one secondary winding, which can be connected to a load via a rectifier circuit comprising at least one diode (2), wherein the switched mode power supply comprises at least one pie comprises at least one secondary winding, which can be connected to a load via a rectifier circuit comprising at least one diode (2), wherein the switched mode power supply comprises at least one piezoelectric fan (8), which brings about an air flow at the transformer (1) and/or at the switching element (4) and/or at the diode (2). The air flow produced can be guided in a targeted manner onto thezoelectric fan (8), which brings about an air flow at the transformer (1) and/or at the switching element (4) and/or at the diode (2). The air flow produced can be guided in a targeted manner onto the components to be cooled, with the air throughflow in total remaining low and therefore also no contamination by means of air particles arising.components to be cooled, with the air throughflow in total remaining low and therefore also no contamination by means of air particles arising.
