A low voltage electromagnetic interference (EMI) filter of an electric vehicle is provided. In the low voltage EMI filter, a pair of Y capacitor units are respectively installed in input and output ends of the low voltage EMI filter. A normal mode (DM) filter and a common mode (CM) filter are installed between the pair of Y capacitor units. The pair of Y capacitor units, the DM and CM filters discharge CM and DM noises generated in a low voltage battery connection unit to a sash GND (earth) step by step and reduce noises of the low voltage battery connection unit.

A cover for covering at least a portion of electrical power distribution equipment, such as an open end of a conduit riser. The cover has a bottom opening for fitting over the open end of the conduit riser. The cover has an upper opening to allow egress of one or more wires from the open end of the conduit riser. The cover can be configured for fitting over conduit risers of various sizes and/or accommodating different numbers or sizes of wires. The cover can include ventilation openings for permitting egress of heat from the open end of the conduit riser.

Linking cable connector includes a lead frame held in an interior cavity of a cover. The lead frame includes conductive leads arranged side by side in a row and extending between a first end and an opposite second end of the lead frame. At least some adjacent conductive leads are spaced on a first lead pitch at the first end, and are spaced on a second lead pitch at the second end. The second lead pitch is less than the first lead pitch. The conductive leads engage and electrically connect to corresponding wire conductors of a first cable harness at the first end of the lead frame, and the conductive leads engage and electrically connect to corresponding wire conductors of a second cable harness at the second end of the lead frame such that the leads provide conductive paths between the first and second cable harnesses.

A grommet attachment structure and a grommet that make it possible to stabilize the force for fixing the grommet to a component. The grommet includes a main body portion that is tubular, lip portions that project from the inner peripheral surface of the main body portion and can come into contact with the outer circumferential surfaces of components, and fold back portions that are provided at positions on the main body portion on end sides in the axial direction relative to the lip portions, and that cover the formation regions of the lip portions when folded back to the outer side.

A power system for a marine ship includes a plurality of protection zones, wherein at least two protection zones are coupled to each other via at least one bus-tie converter. Each of the protection zones includes a plurality of direct current (DC) buses; wherein DC buses which do not have same DC voltage are coupled to each other via at least one DC to DC converter. Furthermore, at least one energy source is coupled to at least one DC bus via a power electronic converter.

Embodiments described herein comprise a cable system. The cable system has a plurality of cables and a plurality of cable hangers. The cable hangers are configured to support the plurality of cables in a building. The plurality of cable hangers have one or more cable supports configured to hold at least one of the plurality of cables and a support configured to couple the cable support to the building.

One end side of a corrugated tube is urged forward or backward in a closing direction, among a circumference direction around a vertical direction passing through the one end of the corrugated tube, in which a slide structural body is closed with respect to a vehicle body so that the corrugated tube is bendable in a U-shape.

An emission protection device including a signal generating unit to generate, for at least one electrical signal relayed by at least one conductor to a load, with which the load is switchable and/or energize-able, at least one electrical output signal, which is phase-shifted by 180° compared to the at least one electrical signal, and an emitting structure, which is connected to the signal generating unit so that the emitting structure is excitable with the at least one electrical output signal to emit an electromagnetic field. Also described is a bridge driver for a load, a controller for a load, and a load, as well as a method for operating a load by switching and/or energizing the load with the at least one electrical signal, generating the at least one electrical output signal, and exciting the emitting structure using the at least one electrical output signal to emit an electromagnetic field.

An electric locomotive includes a first control line and DC buses laid between couplers, a power storage device connected to the DC buses, and a DC/DC converter that executes charge and discharge control with respect to the power storage device. A non-powered vehicle includes DC buses connected to the DC buses via a coupler, a second control line, a power storage device connected to the DC buses via a circuit breaker, and a BMU that manages the power storage device. The DC/DC converter executes power accumulation control with respect to the power storage device and power accumulation control with respect to the power storage device. When having determined abnormality of the power storage device, the BMU controls the circuit breaker to be turned off, thereby cutting off electrical connection between the power storage device and the DC buses.
