FIELD: electricity. ^ SUBSTANCE: combined rectifier comprises diodes (1-9), matching power transformer (10), step-up power transformer (11), capacitors (12, 13) and load (14). To rectify AC voltage and current by combined rectifier, diode (1), primary windings of transformers (10) and (11) are connected serially to each other and source of AC voltage, diode bridge of diodes (2-5) is connected to secondary winding of transformer (10) and capacitor (12), diode bridge of diodes (6-9) is connected to secondary winding of transformer (11) and to capacitor (13), positive pole of diode bridge of diodes (2-5) and capacitor (12) is connected to negative pole of diode bridge of diodes (6-9) and capacitor (13). Load (14) is connected to negative pole of diode bridge of diodes (2-5) and capacitor (12) and with positive pole of diode bridge of diodes (6 - 9) and capacitor (13), with the help of diode (1) half-wave rectification of AC current is carried out, AC EMFs are induced in transformers (10) and (11), which are then rectified by full-wave rectifiers of diodes (2-5) and (6-9), filtered with the help of capacitors (12) and (13), summed by serial connection of diode bridges and capacitors, and total EMF is sent to load (14). ^ EFFECT: improved efficiency. ^ 2 dwg |
