Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a DC power transmission device which can reduce harmonic loss. SOLUTION: In a DC power transmission device, a power conversion device 7 which bridge-connects bulbs 5a-5f formed of a thyristor with three phases and the DC winding wire 4a-side of a transformer 4 are connected, and an AC power is converted into a DC power or DC power is converted into AC power. The commutation of the thyristor is controlled with an inductance obtained by adding the inductance of the transformer 4 and the inductance of a reactor.
