<p>It is possible to provide a power conversion device and a power conversion system capable of reducing the number of switching elements in 3-phase/2-phase conversion so as to suppress cost increase and lowering of conversion efficiency and prevent generation of a higher harmonic. In order to achieve this object, the power conversion device (1) includes input terminals (121 to 123), first output terminals (131, 132), second output terminals (141, 142), and an insulation transformer (11). The insulation transformer includes a primary coil (L1) and a secondary coil (L2) having identical inductance. A first end of the primary coil has polarity equal to a second end of the secondary coil. A first end of the first output terminal is connected to the input terminal and the first end of the primary coil. The second end of the first output terminal is connected to the input terminal and the first end of the secondary coil. The first end of the second output terminal is connected to the second end of the primary coil and the second end of the secondary coil. The second end of the second output terminal is connected to the input terminal.</p> |
