OPERATION METHOD OF CONVERTER DIAGRAM, AND DEVICE FOR METHOD'S IMPLEMENTATION Russian patent published in 2013 - IPC H02M1/12 H02M5/452 H02M7/217 H02P21/00

Abstract RU 2478253 C2

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_A) shaped from control signal (S_R), and control signal (S_R) is shaped owing to adjusting H fraction of higher harmonics of line currents (i_NH) to the specified value (i_NHref) of line current; at that, H=1, 2, 3,…. Specified value (i_NHref) of line current is shaped owing to adjusting the specified value (u_NHref) 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.
