摘要： An in-rush current limiting system has a fast response time so that it can be used with power supplies that turn on and off rapidly. The system dissipates very little power during the normal mode of operation. This is achieved, in various embodiments, by connecting a regulator in series with a load capacitance and in parallel with the system load.

摘要： In the disclosed stepping motor system a band pass filter extracts error signals from currents in a stepping motor driver, and a feedback system delays command pulses to the driver on the basis of the error signals. This suppresses mid-frequency instabilities in the operation of the stepping motor.

摘要： A storage rack system to be installed on a floor has a plurality of columns, is more flexible in a down aisle dimension than it is in a cross aisle dimension, and has at least a first column and a second column adjacent one another in the cross aisle dimension. A storage rack vibration isolator for use with this storage rack system comprises at least one seismic vibration absorption and dissipation structure constructed to be located primarily between the first and second columns to reduce the storage rack system's natural frequency in at least the cross aisle dimension. The seismic vibration absorption and dissipation structure includes a first member connectable to the storage rack system and a second member connectable to the floor. At least one column support assembly is mountable to at least the first and second columns to enable them to move with respect to the floor. A structure limits the movement of the first and second columns to substantially the cross aisle dimension.

摘要： In the disclosed system, a switching circuit energized from a source applies current pulses to the windings of a motor, such as a stepping motor. A chopper regulates the winding currents during each current pulse through four or more control cycles, a power cycle, a circulating cycle, a reset cycle and a second circulating cycle. The chopper enables current from the source to the winding during the power cycle; disables the source and forces residual current entirely within the switching circuit and outside the source during the circulating cycles; and constrains current flow from the winding through the source against the plurality of the source during the reset cycle. Preferably, a second switching circuit energizes a second winding and the chopper times the cycles so that the power cycle in one winding coincides with the reset cycle in the other winding.

摘要： A closed-loop core saturation control circuit for use in pulse width modulated power supplies is disclosed. The circuit uses a single transistor as a unity gain, low impedance track and hold amplifier to sense the current in the primary winding of the transformer and supply a related voltage to the power supply comparator, where it sums with the linear ramp voltage. The on-times of the switching transistors are therefore individually controlled and varied such that both switching transistors will see substantially equal peak currents.

摘要： A storage rack vibration isolator for a storage rack system installed on a floor comprising a first mounting plate connectable to the storage rack system, a second mounting plate connectable to the floor. An elastomeric component extending between these mounting plates and is operatively attached to them so that during seismic events the first and second mounting plates remain attached to the elastomeric component as the elastomeric component is placed in shear while said first and second mounting plates are able to move in planes substantially parallel to each other. The elastomeric component comprises at least one elastomeric member made of material that is capable of absorbing and dissipating the energy of ground movement imparted to the storage rack system during seismic events, while the material enables the storage rack system to move a sufficient distance relative to the floor to lower the natural frequency of the storage rack system in at least one horizontal direction.
