摘要： An active snubber circuit for a switching power supply, in which a main switching element repeatedly operates an on-off operation so that current intermittently flows in a primary coil, has a capacitor for surge voltage absorption, a sub-switching element and a sub-control circuit controlling the sub-switching element. A circuit in which the capacitor for surge voltage absorption and the sub-switching element are connected in series is connected in parallel with the primary coil, and the sub-control circuit turns on the sub-switching element for a predetermined time period just after the main switching element is off.

摘要： A switching power supply has a bottom detection circuit (55), which judges whether or not a bottom has been reached, based on a voltage of a capacitor (C9) that determines an off time of a switching element (Q1) that generates a voltage at the secondary side of a transformer (13) and, in the case in which the judgment is made that a bottom has not occurred, a charging voltage for the capacitor (C9) is switched to a high-potential side.
