Abstract

PURPOSE: To achieve the simplification of circuit constitution and the prevention of arc cutting by providing the first half-wave rectifier circuit between one output terminal and one end of secondary winding and the second half-wave rectifier circuit between the foregoing output terminal and the intermediate tap of the secondary winding both in the same direction.
CONSTITUTION: The voltage on the secondary side of a voltage transformer T' is rectified by the first half-wave rectifier circuit SC1 consisting of output-controlling thyristors TH7 thru TH9 and DC voltage is outputted to both output terminals 2, 3 through a DC reactor DCL. At this time, the output voltage may be controlled like the waveform (a) through phase controlling of the TH7 thru TH9. On the other hand, the voltage of the intermediate tap of the secondary winding T'b is rectified by the second half-wave rectifier circuit SC2 consisting of superposing thyristors TH10 thru TH12. Here, TH10 thru TH12 are fully conducted through firing at AC 0 point, whereby the output voltage like the waveform (b) is obtained. Hence, the voltage shown by diagonal lines is obtained at the output terminals 2, 3 and arc cutting is prevented.
