Document Type and Number:
WIPO Patent Application WO/2020/255662
Kind Code:
A1
Abstract:
Provided is a switched-mode power supply device in which noise is reduced without using a large EMI filter or the like. The switched-mode power supply device 9 is provided with a switching transformer 15 for switching a lower-voltage power supply 12 and supplying power to a control circuit 6 on a higher-voltage power supply 11 side. The switching transformer 15 includes a primary winding 13 on the lower-voltage power supply 12 side and a secondary winding 14 on the control circuit 6 side, and insulates the lower-voltage power supply 12 side and the higher-voltage power supply 11 side from each other, wherein the primary winding 13 and the secondary winding 14 are separated.
