Provided is a rectifier circuit in which the effect of suppressing harmonic components is improved without increasing the number of switching elements and no interphase reactor is required. The rectifier circuit has: a conversion transformer that outputs two sets of three-phase alternating currents having different phases; two sets of bridge circuits respectively converting the three-phase alternating currents to direct currents; and a coupling circuit coupling the two sets of direct current outputs in parallel. The coupling circuit has two switching elements and a DC reactor, wherein one ends of the switching elements are respectively connected to DC output terminals of the two sets of bridge circuits and the other ends are both connected to one end of the DC reactor. |
