Brief description of the drawings
Accompanying drawing 1 is a kind of compound main circuit with paralleing reactor double reverse-stars type controlled rectifier.Wherein：B is that three-phase is whole
Convertor transformer, L are paralleing reactors, and D is diode, and V is IGCT.
Embodiment
Rectifier of the present utility model is described in detail by following specific embodiment.
Accompanying drawing is understood：3 armature winding triangle connections of three-phase rectifier transformer, with centre tapped 3 rectification windings
Connect into double reverse-stars type, 1) 1 low pressure output is formed by paralleing reactor, double reverse-stars type winding, 6 diodes (V1~V6)
Band paralleing reactor double reverse-stars type rectifier, by diode D7, in the pressure rectified current of two DC output ends (1,2) output half
Pressure, has an optimum power factor point, its maximum output current is equivalent to 6 secondary windings Parallel opertations.2) to 6 crystalline substances
During brake tube (V1~V6) 1 trigger signal, 3 secondary commutation windings (a-a ', b-b ', c-c '), 6 diodes (D1~D6) and
6 IGCTs (V1~V6) form a high pressure belt paralleing reactor double reverse-stars type controlled rectification circuit again with paralleing reactor,
