  • Publication number: 20130308359
    Abstract: In some aspects of the invention, a zero current detecting circuit of a switching power supply device detects a gradient of the current flowing in an inductor in the OFF state of the switching element and detects the timing at which the current through the inductor becomes zero corresponding to the detected gradient of the inductor current. Specifically, the zero current detecting circuit receives a signal for controlling ON/OFF driving of the switching element and a voltage signal proportional to the current flowing through the inductor in an OFF state of the switching element. The voltage signal can be compared sequentially with first and second comparison reference voltages to control charging and discharging of a capacitor. Further, the zero current detecting circuit can detect a timing at which the charging and discharging voltage of the capacitor as the timing of zero current flowing through the inductor.

  • Publication number: 20130294125
    Abstract: Aspects of the invention provide an error amplifier that can compare a feedback voltage of an output voltage with a reference voltage to produce a resulting error signal in cooperation with a phase compensating circuit. In some aspects of the invention, an AC detecting circuit makes a decision as to whether a detected input voltage signal is that of a 100 Vac system or that of a 200 Vac system to change the gain of the error amplifier according to the result of the decision. When the voltage signal Vis is lower than the threshold voltage established beforehand, for making the transient response speed of the phase compensating circuit faster, the AC detecting circuit increases the gain of the error amplifier. When the voltage signal is higher than the threshold voltage established beforehand, for making a power factor higher, the AC detecting circuit decreases the gain of the error amplifier.
