摘要： Malfunctions of a switching device included in a power factor corrector are reduced when an instantaneous voltage drop or an instantaneous power failure occurs. If the instantaneous voltage drop or the instantaneous power failure occurs in an AC power source (91) while the power factor corrector (25) is performing a power factor correction operation by boosting an input voltage (V1), an instantaneous power failure controller (31 g) turns off the switching device (Q25a, Q25b, Q25c) included in the power factor corrector (25) so that the power factor correction operation stops. When the commercial power source (91) recovers, too, the power factor corrector (25) suspends the power factor correction operation.

摘要： Reduced is occurrence of hunting in which a power factor corrector continuously turns on and off alternately for a short period of time. A power factor correction controller (31g) turns on a power factor corrector (25) if a parameter value for an input current (Im) into the power factor corrector (25) is greater than or equal to a first threshold, and turns off the power factor corrector (25) if the parameter value is smaller than or equal to a second threshold below the first threshold. Through a predetermined time period (Tg) from a moment when the power factor corrector (25) is switched either from on to off or from off to on, the power factor correction controller (31 g) maintains a state of the switched power factor corrector (25), regardless of the parameter value.

摘要： Disclosed herein is a technique for substantially preventing, in a power converter including a boost power factor correction section, the power factor correction section from starting an intermittent operation even if the ripple voltage of its smoothing capacitor has increased. The converter includes: a power factor correction section (25) including a booster circuit (25a) boosting an input voltage (V1) supplied from a rectifier section (22) and a smoothing capacitor (26) smoothing an output of the booster circuit (25a); and a control section (30, 31) correcting a power factor by controlling the booster circuit (25a). The control section (30, 31) makes correction to the amount of boost of the booster circuit (25a) such that an output voltage (V2) of the smoothing capacitor (26) does not become lower than the input voltage (V1).
