Abstract: A solid-state direct replacement relay assembly, and a method for installing and using it to replace the mechanical-style relays in the electrical cabinets of a locomotive. Solid-state relay components are substituted to upgrade locomotive relay systems, and to improve train controls. Normally solid-state relays cannot directly handle standard locomotive voltages without an external power supply that requires modification to the original train design and wiring. The solid-state relay assembly is coupled to a D.C./D.C. converter, which steps 75 volts down to approximately 5–32 volts, and is used to control the solid-state relay assembly. The use of the solid-state relay assembly device requires no modification to the existing electrical wiring system of any new or old locomotive.

Abstract: An improved snubber is electrically switched to close a current path to a capacitor (C) in a series connected RC circuit at the onset of an abrupt voltage change otherwise producing ringing in a resonant circuit to which the snubber circuit is connected. The current path to the capacitor (C) is then interrupted before the capacitor (C) discharges and thereafter at each such voltage change in the resonant circuit the capacitor (C) is no longer charged from its totally discharged state but nevertheless damps the ringing by virtue of current flow to the nearly completely charged capacitor (C). By preventing complete charging and discharging of the capacitor (C) in the RC circuit every cycle, power dissipation in the resistance of the snubber circuit is greatly reduced.

Abstract: An active snubber circuit having a controllable dV/dt. The circuit includes a power device and surface mount components including a resistor having a value selectable to control the dV/dt. The use of surface mount components achieves a low profile, small size circuit that can advantageously be used to eliminate noise generated by contact arcing, to dissipate arc energy while clamping to a predetermined voltage value, and in power conversion applications to provide a desirable dV/dt, among other applications.

Abstract: A method for clusterized power sharing conversion and regulation of the primary source power within the power converting and regulating supplies includes performing simultaneously and indispensably a procedure of subdividing every switch-mode power conversion process into multiples of sub-processes, each performed with a less intensive power draw within a separate power conversion channel, a procedure of time-displacing these sub-processes and a procedure of overlaying the power shares drawn through the separate power conversion channels. When applied to the power supply systems these procedures are performed within the summing circuits between primary power sources and power converting apparatus and loads. The improved method offers a procedure of subdividing the multiple power conversion power-on cycles into a number of separate clusters each containing at least one or more power-on cycles, a procedure of time-displacing the clusterized power-on cycles with respect to each other within the same cluster, a procedure of summing the portions of power drawn through the same cluster, a procedure of time-displacing the clusters, a procedure of summing the shares of power drawn through all clusters, and a procedure of controlling the time-displacement intervals to provide optimal superimposition of power shares drawn through the system which results in improvement of ripple filtering, efficiency and rate-of-response to changes in load.
