Definitions

  • Each of the other arms 12 to 16 has the same configuration as the arm 11.
  • Each of the arms 12 to 16 includes N thyristors Q1 to QN connected in parallel.
  • the gates of thyristors Q1 to QN of arms 12 to 16 receive gate pulse signals G2 to G6 from control device 2, respectively.
  • the control device 2 operates in synchronization with the three-phase AC voltages Va, Vb, and Vc from the AC power supply 3, and generates gate pulse signals G1 to G6 so that the DC output voltage VDC becomes the target DC voltage VDCT. Give to arms 11-16.
  • the tip of the anode electrode 31 of the thyristor Q1 is connected to the surface of the first portion 21b of the conductor 21.
  • the tip of the anode electrode 31 of the thyristor Q2 is connected to the surface of the second portion 21c of the conductor 21.
  • the tips of the anode electrodes 31 of the thyristors Q2 to Q8 are connected to the end of the conductor 21 on the left side (conductor 22 side).
  • FIG. 5 is a front view showing the configuration of the arm 14 shown in FIG. 1, and is a view compared with FIG. Referring to FIG. 5, arm 14 differs from arm 11 in that the directions of thyristors Q1 to Q8 are reversed, the upper end of conductor 22 constitutes anode terminal 14a, and the right end of conductor 23 is the cathode. This is the point constituting the terminal 14b.
  • the cathode electrode 32 (first electrode) of each of the thyristors Q1 to Q8 extends in the right direction in the drawing.
  • the tip portions of the cathode electrodes 32 of the thyristors Q1 to Q8 are distributed in the length direction of the conductor 21 and connected to the surface of the conductor 21.

Abstract

Selon la présente invention, un bras (11) d'un redresseur à thyristor comprend : des premier et second conducteurs (21,22) ; et des premier à huitième thyristors (Q1-Q8). Les premier à huitième thyristors (Q1-Q8) sont agencés séquentiellement dans le même sens que celui des premier et second conducteurs (21, 22), ont des électrodes d'anode respectives (31) connectées au premier conducteur (21), et ont des électrodes de cathode respectives (32) connectées au second conducteur (22). Une fente (21a) destinée à augmenter l'impédance d'un trajet de courant (P1) du premier thyristor (Q1) est formée dans le premier conducteur de façon à réduire la variation de courants (Iq1-Iq8) des premier à huitième thyristors (Q1-Q8).
