    Abstract: A dynamic braking circuit is disclosed that can be operated with stability over both high and low speed regimes. This circuit has the advantage of using fewer components than previous circuits. In addition, when in braking mode, the armature and field currents tend to oppose each other across the main braking switch hence reducing electromechanical stresses when in high current regime. According to a second invention, a dynamic braking circuit is disclosed to implement a "soft" extended braking function with the capability of providing a smoother braking action at high braking effort at little extra cost resulting from the replacement of a contactor by a reverser. The main advantages of this preferred embodiment are that the current generated by the armatures during braking can be controlled independently from the excitation of the field windings at low speeds and that it enables simultaneous self supply, regeneration and dynamic braking.

    Abstract: The present invention is directed to the design of a load-lifting apparatus comprising one or more prime power sources, one or more energy storage systems and a means of regenerative braking. Regenerative energy is recovered when the load-lifting apparatus lowers its load. The elements of the prime power sources, energy storage devices and electrical components may be distributed to provide stability for the load-lifting apparatus. The general power architecture and energy recovery method can be applied to cranes, rubber-tired gantry cranes, overhead cranes, mobile cranes, ship-to-shore cranes, container cranes, rail-mounted gantry cranes, straddle carrier cranes and elevators. In such an architecture, the energy storage system helps alleviate the power rating requirement of the prime power source with respect to the peak power requirement for lifting a load.
