The invention relates to a circuit assembly (1) and to a method for elective control of an alternating current motor (3) or direct current motor (2) supplied from a direct voltage source (4). The circuit assembly (1) comprises two converter modules (5, 6) having an equal number of half-bridges (7) and a number of bridge suction throttles (14.1, 14.2, 14.3) corresponding to the number of half-bridges (7) in a converter module (5, 6) and a control unit (12) for actuating the half-bridges (7) of the converter modules (5, 6). The converter modules (5, 6) are operated to control an alternating current motor (3) as an inverter and to control a direct current motor (2) as a direct voltage converter. |
