COMBINED RECTIFIER

摘要

The invention relates to the field of electrical engineering and is intended in particular for converting an AC voltage and an alternating current into a DC voltage and a direct current. The combined rectifier comprises: a matching power transformer and a step-up power transformer, the primary windings of said transformers being connected in series with one another and with an AC voltage source, and the secondary windings being connected in series with diode bridges, wherein the positive terminal of the diode bridge of the matching transformer is connected to the negative terminal of the diode bridge of the step-up transformer; and a load, which is connected to the negative terminal of the diode bridge of the matching transformer and the positive terminal of the diode bridge of the step-up transformer. The combined rectifier additionally comprises a half-wave rectifier and capacitors, wherein the half-wave rectifier is in the form of a diode and is connected in series with an AC voltage source and the primary winding of the matching transformer, and each capacitor is connected to the diode bridge of the corresponding transformer. When implementing the claimed invention it is possible to achieve the technical result of reducing losses during conversion of an AC voltage and an alternating current into a DC voltage and a direct current.
