    Abstract: In a switching power supply, primary-side MOS transistors are alternately turned on, so that a resonant current flows into the primary winding of a transformer and an alternate power is transferred to the secondary side. The alternate voltage generated at the secondary winding is applied by the voltage generated at the wound-up secondary winding to the gates of secondary-side MOS transistors such that they are turned on respectively in periods when the polarity of the voltage is positive. Rectified currents flow into a capacitor through a choke coil to perform synchronous rectification. If the voltage of a smoothing capacitor becomes higher than the alternate output voltage when the transformer is inverted, reverse currents flow into the secondary-side MOS transistors. With the counterelectromotive force of the choke coil, the reverse currents flowing when the transformer is inverted are suppressed, and the efficiency of the switching power supply is prevented from decreasing.

    Abstract: PURPOSE:To reduce loss and noise by a method wherein the rise-up of an output current is detected other than a secondary output to control the frequency as well as the duty(DT) of a driving power source. CONSTITUTION:A secondary winding is provided separately in a switching(SW) transformer 3 to detect the current I20 of the secondary winding upon the rise-up of the same. When the fluctuation of the output current I20 is small, a switching regulator circuit 20 is operated with the proper frequency of the same and the duty of a power source is controlled in accordance with the output current I20. When the output current I20 is increased, the duty of the power source is controlled so as to increase the frequency of the same and a collector current 110 is cut before the rise-up of a collector voltage E10 whereby the increase of a loss in a switching transistor 4 may be avoided. When the output current I20 is reduced, the duty of the power source is controlled so as to decrease the frequency of the same and the switching transistor 4 is switched to ON before the breaking of the collector voltage E10 while being oscillated whereby the generation of noise may be prevented.

    Abstract: PURPOSE:To keep the over current generation time percentage within the allowable limit by causing a capacitance element to charge or discharge depending on detection whether a detected current has exceeded the predetermined value or not and by controlling operations of the circuit to be protected by detecting a terminal voltage of the capacitance element. CONSTITUTION:A first voltage detecting circuit 1 detects whether the voltage Vs converted from the current To has exceeded or not the predetermined threshold value, while a charging/discharging circuit 2 charges or discharges a capacitance element Cx with detected/undetected output of the first voltage detection circuit 1. Next, a second voltage detecting circuit 3 detects whether a terminal voltage Vx of the capacitance element Cx has exceeded or not the predetermined value and the detection result is outputted in the high or low logical level. Operation of the circuit 5 to be protected is controlled by a holding output of the holding circuit 4. Thereby, the protecting operation for keeping an over current generation time percentage within the allowable limit can be realized.
