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： To prevent a switching element from being destroyed by a reverse recovery current, a reverse recovery current prevention device (2) comprises a full wave rectifier (21), first and second diodes (D22, D23), a switching element (24), and a switching element control unit (30). The full wave rectifier (21) rectifies a power source voltage (Vac) from an alternating current power source (10) inputted into first and second input terminals (s2, t2). Each of the anode terminals of the first and second diodes (D22, D23) is respectively connected to the first and second input terminals (s2, t2) of the full wave rectifier (21). The switching element (24) opens or shorts an electrical circuit between a negative-side output terminal of the full wave rectifier (21) and each of the cathode terminals (s3, t3) of the first and second diodes (D22, D23). The switching element control unit (30) prohibits the switching element (24) from shorting the circuit between the negative-side output terminal and each of the cathode terminals (s3, t3) in a case where the voltage between the negative-side output terminal and each of the cathode terminals (s3, t3) is at or greater than a threshold.
