ABSTRACT:
To increase the output voltage of a conventional rectifier bridge, one winding of an autotransformer is connected across a pair of a-c input terminals of the bridge through a thyristor which is turned on only when an output voltage increase is desired, and an extra diode is used to connect the other autotransformer winding to one of the d-c output terminals so that the boost voltage induced in the latter winding is added to the input voltage.
