<p>1296210 Semi-conductor assemblies JOSEPH LUCAS (INDUSTRIES) Ltd 16 April 1970 [9 June 1969] 29033/69 Heading H1K A multiphase alternator rectifier assembly 14 comprises three arcuate terminal plates 15, 16, 17 mounted face to face on alternator frame 17 having a first set of semi-conductor diodes 18, 19, 21 mounted in recesses of plate 15 to which their anodes are connected, a second set of diodes 22, 23, 24 mounted in recesses of plate 16 with cathodes connected thereto, and a third set of diodes 25, 26, 27 mounted in recesses of plate 17 with anodes connected thereto; the plate surfaces being insulatedly coated and facially abutted to be in heat exchange relation interse and with frame 11. The cathodes of the first set and the anodes of the second and third sets are connected to delta phase points of the alternator windings so that direct voltage appears across the first and second plates, 15, 16 and the third plate 17 develops a voltage regulator input. Projections overlie the plate recesses on the sides opposite thereto and are accumulated in apertures of adjacent plates and frame 11, and diodes 18, 22, 25; 19, 23, 26; 21, 24, 27 are adjacently grouped, while the respective anode and cathode leads 31 are lead through apertures of the plates to three-legged insulated phase connectors 32, 33, 34 secured by phase winding terminals 32a, 33a, 34a.</p> |
