Electronic actuator includes several different actuators with control systems. Actuators (M1,M2) are connected in series or parallel and the control systems include a single electronic power circuit (P1-P4). Power circuit has H type transistor bridge circuit and actuators are connected in series between two middle points of bridge. Control systems have switch connected in parallel with each actuator with bi-directional current control. Alternatively the actuators are connected in parallel between the two middle points of the H type bridge. The control system has a switch (T) having a first terminal connected to one of the middle points of the bridge, and a series of second terminals connected to different actuators. The switch is bi-directional current controlled. An Independent Claim is also included for: a three arm transistor bridge. |
