Title:
DISCHARGE CIRCUIT FOR A RECTIFIER MODULE IN A MOTOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2013/092031
Kind Code:
A3
Abstract:
The invention relates to a rectifier circuit (4) comprising at least two sub-modules (22) in a series connection that draws electrical power via an inductance (20) from a power source (8) emitting a direct voltage (18). Each sub-module (22) has one single phase half bridge (52) on the input side (26, 28) and one single phase full bridge (54) on the load side (30, 32), wherein an intermediate circuit capacitor (34) is connected parallel to the half bridge (52) and to the full bridge (54). According to the invention, each sub-module (22) is connectable to a discharge circuit (36) for discharging the intermediate circuit capacitor (34) and movable between at least two positions, wherein each sub-module (22) is connected in a discharge position to the discharge circuit (36) and in an operating position to the series circuit on the input side (26, 28) and on the load side to a load (10) that is connectable to the sub-module (22).
