AC-TO-AC VOLTAGE CONVERTER Russian patent published in 2018 - IPC H02M7/217 

FIELD: electricity.

SUBSTANCE: invention relates to the AC-to-AC voltage converter (1) comprising the first and second input lead (ACin1, ACin2) of the alternating current, as well as the first and second output lead (ACout1, ACout2) of the alternating current. An input device (Bin) is connected between an input node (11), a common node (12), a positive lead (DCP) of the direct current and a negative lead (DCN) of the direct current. The input node (11) is connected to the first input lead (ACin1) of the alternating current through the first input inductance (Lin1). An output device (Bout) is connected between an output node (13), the positive lead (DCP) of the direct current and the negative lead (DCN) of the direct current. The output node (13) is connected to the first output lead (ACout1) of the alternating current through the output inductance (Lout1). A common device (Bc) is connected between a common node (12), the positive lead (DCP) of the direct current and the negative lead (DCN) of the direct current. The common node (12) is connected to the second input lead (ACin2) of the alternating current through the common inductance (Lc). A control device for controlling the switches of the output device (Bout) and the common device (Vs) is provided. The output device (Bout) comprises the first and second output switches (Sout1, Sout2). The common device (Bc) comprises the first and second common switches (Sc1, Sc2). The second input lead (ACin2) of the alternating current is connected to the second output lead (ACout2) of the alternating current. The input device (Bin) comprises the first and second diodes (Din1, Din2) and a bidirectional switch (BS) connected between the input node (11) and the common node (12). The control device also controls the bidirectional switch (BS).

EFFECT: improvement of mass-dimensional parameters and improvement of the possibility of regulating the converter output power.
