The rectifier bridge generally has a large enough inductive load, so the rectifier bridge does not appear current interruption. In the general application of rectifier bridge, the load end is often connected with a flat wave reactor, so the load can be regarded as a constant current source. Multiple groups of three-phase rectifier Bridges are connected to each other so that the harmonics generated by the rectifier bridge circuit cancel each other. According to the type of rectifier transformer, it can be divided into traditional multi-pulse transformer and auto-type multi-pulse transformer. The traditional multipulse transformer uses isolation transformer to isolate input voltage and output voltage, but the equivalent capacity of the rectifier transformer is large and the volume is huge.

The load of a general rectifier bridge can be regarded as a constant current source because it is often connected with a flat wave reactor at its load end. In addition, according to EMI measurement standards, in order to reduce the influence of network impedance on measurement results, it is necessary to connect a linear impedance stabilization network (LISN) at the grid input of the rectifier bridge.
