  • Patent number: 11005408
    Abstract: The invention relates to the protection of an electric drive system. If a voltage spike occurs on the input of a current converter of the electric drive system via the intermediate circuit, then in order to dissipate said voltage spike in the electric drive system, a change is made to and fro between a motor operating mode and a generator operating mode in order to dissipate the electrical energy from the intermediate circuit capacitor. For the motor operating mode and the generator operating mode, in each case suitable space phasor vectors can be predefined. This permits particularly simple and rapid activation in order to dissipate the electrical energy in the electric drive system.

  • Patent number: 11006220
    Abstract: A multi-stage mechanical suspension system extends a linear operating range for a loudspeaker and prevents mechanical damage on explosive peaks. The system includes a pair of spaced contact receivers that limit the travel of a contactor. The system provides a flat linear response at low frequencies as the contact receivers are intermittently or occasionally contacted by the contactor during operation of the loudspeaker. The system enables creation of different regions of non-linearity within a total stiffness versus deflection curve of a loudspeaker suspension system. The non-linearity in each region can be controlled individually, so long as the non-linearity by region increases moving away from the rest position. Thus, a plateau of substantially linear stiffness may extend for a large portion of the total displacement allowed for a voice coil and suspension components before a region of non-linear stiffness occurs only at the ends of an allowable excursion to limit the motion.
