    Tips: Isolated DC-DC converter working principle

    The input circuit rectifies and filters the alternating current into direct current, and controls the energy storage of the primary winding of the transformer through the periodic on-off of the power switch tube, and converts the direct current voltage into a high-frequency square wave voltage, which is boosted or stepped down by the transformer, and then rectified. Filtering becomes DC voltage or current.
