FIELD: electricity. ^ SUBSTANCE: electric power supply (IP) of electromagnetic compensators (EMK) consists of DNVS (1), IZV (2), the first (3) and the second (4) adders, phase-shifting pulse-width modulation converter (5), HF filter (6), VK (7), comparator (8), DPVN (9), inverter (10), FSI (11), DTI (12), DVT (13) and load (14). Connection of the above elements of IP circuit of EMK forms two feedback loops: one for current and the other one for voltage. Such circuit provides the possibility of suppressing the pulsations of output current and interference of the network for arbitrary types of load, active and reactive, without reducing the efficiency of the device. ^ EFFECT: reaching deeper suppression of appearing current pulsations and providing protection against pulse interference. ^ 2 dwg |
