A rectifier device is made up of multiple stages of cascaded single-phase mixed bridges consisting of thyristors and diodes.The AC terminal of each mixed bridge is connected to each secondary winding of a transformer whose secondary windings are divided into multiple pieces. is,
Each mixing bridge is fired according to some determined order. The problem with this arrangement is that it creates a fairly large imbalance in the effective current flowing on the AC side of each mixing bridge. This current imbalance is further amplified by a filter connected to the alternating current side of the rectifier for power factor correction. The unbalance of the AC side RMS current of each mixed bridge causes the inconvenience of making the thickness of the transformer secondary winding unbalanced or deciding the thickness of the secondary winding according to the largest RMS current. I will invite you.

均化を図ることができる。 FIG. 2 shows the control sequence of the rectifier shown in FIG. 1. As the control command voltage increases, the first mixing bridge MRF1, the second mixing bridge
The ignition operation is performed in the order of MRF2,... For this reason, the current on the alternating current side of the mixing bridge has the longest circulation period in the first mixing bridge MRF1, and becomes shorter as it approaches the fourth mixing bridge MRF4. In other words, the AC side effective value current is largest in the first mixing bridge MRF1, and in the fourth mixing bridge MRF1.
It becomes smaller as it approaches MRF4. Therefore,
The power factor correction filter 1 is connected to the fourth mixing bridge MRF.
When installed on the AC side of 4, the 4th mixing bridge
The power factor of the current flowing to the AC side of the MRF 4 increases, and the effective value of the effective current increases. That is, it is possible to average the AC side effective value currents flowing through each secondary winding of the transformer 3.
