An electromechanical converter with a rectification function comprises an AC motor 1, FIG. 1, mechanically coupled to an alternator 2, a diode 3, bridge rectifiers 4, 5, matching power transformers 6, 7, capacitors 8, 9 and a load 10, the primary windings matching power transformers 6 and 7 are connected in series with each other, a diode 3 and an alternating current generator 2, inputs of bridge rectifiers 4 and 5, respectively, are connected to the secondary windings of matching power transformers 6 and 7, respectively o, the outputs of which are connected in parallel to the capacitors 8 and 9, respectively, which are connected in series with each other and the load 10. The electromechanical converter with rectification function operates as follows. The alternating voltage of the alternating current source feeds the alternating current motor 1, which rotates the alternating current generator 2, the alternating voltage from which is supplied to the circuit, and diode 3 produces a half-wave rectification of alternating voltage. A half-wave current flowing through the primary windings of the matching power transformers induces a magnetic flux in their magnetic circuits, as a result of which the induction and self-induction EMF is induced in the windings of these transformers, with the help of which the negative half-cycle is restored. Then the resulting voltage is rectified and filtered using bridge rectifiers 4, 5 and capacitors 8 and 9, respectively. Due to the series connection of the two above-mentioned bridge rectifiers and the load, the voltage on the latter is the sum of the voltages of these two rectifiers.

They show the input alternating voltage Uin., The current flowing through the diode 1 Iin.
