A power converting apparatus includes a rectifying circuit having a pair of AC power input terminals and a pair of rectified voltage output terminals; a reactor; and a charging and discharging circuit connected between the rectified voltage output terminals. The charging and discharging circuit includes a first condenser connected with one of the rectified voltage output terminals and one of the AC power input terminals; and a second condenser connected with the other of the rectified voltage output terminals and the one AC power input terminal. The reactor generates a resonance current together with the first condenser and the second condenser, and the second condenser discharges to zero voltage while the first condenser is charged.
