FIELD: electricity.SUBSTANCE: in operation method of converter diagram containing a converter unit with multiple controlled power semiconductor switches and connected to alternating voltage electric mains, controlled power semiconductor switches are operated by means of control signal (S) shaped from control signal (S), and control signal (S) is shaped owing to adjusting H fraction of higher harmonics of line currents (i) to the specified value (i) of line current; at that, H=1, 2, 3,?. Specified value (i) of line current is shaped owing to adjusting the specified value (u) of line voltage. Besides, device for the method's implementation is described.EFFECT: reduction of fraction of higher harmonics in voltages of electric mains of alternating voltage.12 cl, 3 dwg |
