Abstract
A startup method of a semiconductor transformer, according to the present invention, comprises: a link capacitor initiating step in which a control unit controls a link capacitor voltage of a link capacitor between an AC/DC converter and a DC/DC converter connected thereto in series to reach an initial reference value, and stores link power; an output capacitor initiating step in which the control unit controls an output capacitor voltage of an output capacitor configured in an output of the DC/DC converter to reach an initial reference value, and stores output power; a link capacitor stabilizing step in which the control unit controls the link capacitor such that the link capacitor voltage of the link capacitor reaches a stable reference value; and an output capacitor stabilizing step in which the control unit controls the output capacitor such that the output capacitor voltage of the output capacitor reaches a stable reference value.
