Abstract
A power converter in a powered device (PD) of Power-over-Ethernet (PoE) system and a control method are provided. The power converter includes a transformer, a PD interface, a primary-side controller and a detecting circuit. The PD interface receives an input voltage to determine a PoE protocol type of the input voltage, so as to generate a first power type signal. The primary-side controller receives the first power type signal to adjust a primary-side control signal, wherein a primary-side switch is controlled by the primary-side control signal. The detecting circuit detects a mapping signal generated in a secondary-side winding according to the primary-side control signal to generate a second power type signal, wherein the second power type signal indicates the PoE protocol type of the input voltage.
