Abstract:
An AC-DC converting apparatus includes: a boost circuit including a reactor supplied with power supply voltage output from an alternating-current power supply, a first leg including a first upper-arm element and a first lower-arm element connected in series, and a second leg connected in parallel with the first leg and including a second upper-arm element and a second lower-arm element connected in series, and boosting the power supply voltage; and a first voltage detecting unit detecting the power supply voltage. When the power supply voltage is positive, the AC-DC converting apparatus causes the first lower-arm element and the second upper-arm element to perform boosting operation alternately every power supply cycle that is cycle of the power supply voltage, and when the power supply voltage is negative, the AC-DC converting apparatus causes the first upper-arm element and the second lower-arm element to perform boosting operation alternately every power supply cycle.
