Abstract
Device for controlling at least one electric servomotor with high power from a low-voltage network, in particular for motorizing a turret on a tank, characterized in that it comprises, in combination: a voltage booster converter (C), a reversible chopping amplifier (A.sub.1, A.sub.2) fed by the converter (C) and delivering the current required by the motor to be controlled (M.sub.1, M.sub.2) which is of the type able to operate as a generator, and a capacitive type electric energy accumulator (B) inserted between the converter (C) and the amplifier (A.sub.1, A.sub.2).
Claims4
Device for controlling one or more electric servomotors on board a vehicle with high power from a low voltage network comprising:
- a uni-directional monoquadrant voltage booster converter (C);
- a first bi-directional chopping amplifier (A1) fed by the uni-directional converter (C) and delivering the current required by a first servomotor (M1) to be controlled which is of the type able to operate as a generator;
- a capacitive type electric energy accumulator (B) comprised of a set of capacitors connected in parallel, inserted between the uni-directional converter (C) and the first bi-directional chopping amplifier (A1);
- and
- wherein the vehicle is a tank, which tank includes a turret that is motorized about its lateral deflection axis by said first servomotor (M1) controlled by said first chopping amplifier (A1), a weapon carried by the tank turret motorized about its elevational axis by a second servomotor (M2) controlled by a second chopping amplifier (A2), and with both said first and second amplifiers (A1;
- A2) being simultaneously fed by the uni-directional booster converter (C).
