<P>PROBLEM TO BE SOLVED: To obtain an AC-AC power converter capable of suppressing am increase in inductance of a main circuit by achieving a terminal block structure in which main circuit conductors can be kept in parallel as much as possible. <P>SOLUTION: The converter housed in a case and used to convert AC power into DC power is provided with positive and negative main circuit conductors 2, 3 having positive and negative conductor portions 2y, 3y which are each connected to a positive electrode terminal 1b and a negative electrode terminal 1a of each of smoothing capacitors 1, and led out to the outside of the case with insulating sheets 4 sandwiched, and positive and negative terminal block electrode portions 2z, 3z formed by bending the tips of the positive and negative conductor portions 2y, 3y; and a terminal block 10 having a clip groove for sandwiching the positive and negative conductor portions 2y, 3y led to the outside of the case so that they are not separated, a pedestal for placing the positive and negative terminal block electrode portions 2z, 3z is formed, and attached to the outside of the case in a state where the positive and negative conductor portions 2y, 3y are sandwiched in the clip groove. <P>COPYRIGHT: (C)2008,JPO&INPIT |
