The SCMs mainly perform classification and testing for each rectifier and the PC accomplishes data display,counting,storing,printing and other functions about the test.

There are two routes of load transfer in the integral deck with multi-transversal beams.

This paper introduces the structural design of a railway steel truss girder used with steel orthotropic deck plate,analyzes the functions and significance of the truss girder used with such type of the integral deck structure to high-speed traveling of trains and also makes a study of the mechanical behavior of the girder after it is used with the deck structure.

Considering existing limitation,a full-fresh voltage multiplying bridge rectifier circuit is presented,and the theoretical derivation and numerical simulation are carried out.

To reform planing machine made in home,using rectifier bridge,which is mainly consisted of rectifier diode,to replace of directcurrent exciter in Shiheng special steel works.

The modes of automobile alternator driving at home and abroad are classified according to the matching mode of voltage regulator and rectifier bridge.

This DC side APF is equipped between rectifier bridge and load to compensate the harmonic source by producing harmonic voltage, making the supply current has same phase and shape as the supply voltage.
