Zusammenfassung:PROBLEM TO BE SOLVED: To provide a DC converter that is capable of supplying DC power to respective two apparatuses using voltages whose values differ from each other and enables the two apparatuses to share and use regenerative power output from the respective apparatuses.SOLUTION: A DC converter comprises: an AC power output unit 13 that has a structure of three-phase four-wire star-connection and outputs three phase AC power from three-phase output wires u, v, w of the star connection; a three-phase rectifier 16 that receives, as input, three-phase AC power from the three-phase output wires u, v, w, rectifies the input three-phase AC power to generate DC power, and outputs DC power from a positive electrode and negative electrode output wires l1, l2; a capacitor 17 connected to a point between the positive electrode output wire l1 and a neutral wire o of the star connection; and a capacitor 18 connected to a point between the negative electrode output wire l2 and the neutral wire o.SELECTED DRAWING: Figure 1 【課題】異なる値の電圧を使用する2つの機器のそれぞれに直流電力が供給可能であって、かつそれぞれの機器から出力された回生電力を2つの機器の間で共有して使用可能な直流変換装置を提供すること。【解決手段】本発明にかかる直流変換装置は、3相4線のスター結線構造を有し、スター結線の3相の出力線u、v、wから3相交流電力を出力する交流電力出力部13と、3相の出力線u、v、wから3相交流電力が入力され、入力された3相交流電力を整流して直流電力を生成し、正極及び負極の出力線l1、l2から直流電力を出力する3相整流器16と、正極の出力線l1とスター結線の中性線oとの間に接続されるコンデンサ17と、負極の出力線l2と中性線oとの間に接続されるコンデンサ18と、を備える。【選択図】図1
