With DC power supply 60-fold pulse frequency

摘要

DC voltage source with 60-times the frequency of pulsations for converting AC to DC to power the electric traction loads transport electrotechnological power plants and obtaining high voltage DC power lines. Comprises a transformer power variable EDS1 with the primary windings 2, 3, 4 of the transformer connected in a star (delta), with the secondary windings 5 ​​and 6, 7, forming source orthogonal EMF, the windings 6, 7 are connected in-series and the other secondary windings connected to respective pairs 8 and 9, 10; 11 and 12, 13; 14 and 15, 16; 17 and 18, 19; 20 and 21, 22, 23 and 24, 25; 26 and 27, 28; 29 and 30, 31; 32 and 33, 34; 35 and 36, 37; 38 and 39, 40; 41 and 42, 43; 44 and 45, 46; 47 and 48, 49, forming orthogonal sources of EMF; one hundred and twenty valves 50 ... 169 form a rectifier pyatnadtsatistupenchaty fifteen chetyrehyacheykovyh rectifier bridges connected in series outputs of different polarities, wherein each bridge is connected to AC input with a pair of orthogonal emf, and the extreme free outputs bridges 170 form the anode formed by valves 166 ... 169 and a cathode 171 formed by gates 50 ... 53 conclusions output devices connected to the load 172. The DC voltage source with 60-fold provides a three-channel frequency ripple 20 bullets Noah straightening.
