Beschreibung
Zusammenfassung:	A power circuit of a traction drive with alternating-current motor and safety relay of brakes which consists of a voltage converter, output LC filter, brake safety relay (5), current transformer (6), current alternator (8) and alternating traction drive (9). The voltage converter is made in the shape of a two-quadrant converter (1), formed by the first switchable reverse conducting element (2) and second switchable reverse conducting element (3), connected together in series. The two-quadrant converter (1) is connected by the inputs to the direct-current supply voltage and its first output (11) is connected through a series combination of filtration inductance (4) of the brake safety relay (5) and current transformer (6) to the first terminal of filtration condenser (7) and first input (81) of the current alternator (8). The second output (12) of the two-quadrant converter (1) is connected to the second terminal of the filtration condenser (7) and with the second input (82) of the current alternator (8), whose outputs are connected to the alternating traction drive (9).
