POWER SUPPLY TO BRIDGE RECTIFIERS PARALLEL CONNECTED ON OUTPUT SIDE WITH VOLTAGES OF SECONDARY WINDINGS AT LEAST OF ONE TRANSFORMER, WHICH ARE TURNED AS TO PHASE

摘要

FIELD: electricity.;SUBSTANCE: device is equipped with parallel connected diode bridges (8) which are powered through at least one transformer; at that, secondary voltages have various phase turns on secondary windings (5, 6) of transformer. Transformer has two in-series connected primary windings (1, 2) to which AC voltage of public network is supplied, and diode bridge (8) which consists of three pairs of diodes is connected to each secondary winding (5, 6) of transformer. Various phase turns in the device are determined by the fact that one secondary winding of transformer is connected as per triangle circuit, and the other secondary winding is connected as per star circuit.;EFFECT: maximum smoothness degree of voltage at easy and reliable operation of the device.;3 cl, 2 dwg
