Beschreibung
Zusammenfassung:	The invention provides a switching converter, which can realize voltage isolation and zero ripple input of the whole converter so as to reduce low-frequency conduction noise. An inductor and a transformer in the converter are integrated on one magnetic device, so that a basis is provided for integrally realizing a high-integration-level small-volume power supply. 本发明提供一种开关变换器，既可以实现电压隔离，就可以实现整个变换器的零纹波输入，从而降低低频传导噪声。而且变换器中的所用电感和变压器都集成到一个磁性器件上，为整体实现高集成度小体积电源提供基础。
