The present invention relates to a bogie structure for a mountain railway car. The bogie structure is configured as follows: a traction motor for driving an axle of mountain railway car is installed on a car body to simplify the bogie structure and to minimized interference between the traction motor and other components constituting the bogie, and a first and a second bearing are respectively inserted and installed between a first and a second axle and a first and a second wheel, so that a first and a second wheel located in one side close to a turning center are rotated less than a first and a second wheel located in the other side opposite thereof and a traveling distance of the wheels located in the turning-centered side is generated corresponding to a length of a turning-centered side railway, whereby the mountain railway car is improved in traveling stability.

Disclosed is a method for balancing at least one component of the power supplied by two inverters powered in parallel in a power grid of a railway vehicle, the method including:—a step for measuring the variation of a component of a current supplied by a first inverter, in order to obtain a measured variation; and—a step for modifying a control setpoint of the first inverter as a function of the measured variation.

A semiconductor device of an embodiment includes a SiC layer including a first trench, a second trench having first and second regions, an n-type first SiC region, a p-type second SiC region, an n-type third SiC region, a p-type fourth SiC region between the first trench and the first SiC region, and a p-type fifth SiC region between the second trench and the first SiC region and having a first portion and a second portion, a gate electrode in the first trench, a first electrode in the second trench, and a second electrode. A distance between the first trench and the first region is greater than a distance between the first trench and the second region, the first portion is separated from the fourth SiC region, the second portion contacts the fourth SiC region, the first region contacts the first portion, and the second region contacts the second portion.

Railway system includes a railway vehicle movable along a railway guide system, the railway vehicle including a chassis and a carriage rotatably supported on the chassis via a pivot coupling. The railway vehicle further includes a pivot actuation system including an actuator and a control system connected to the actuator and to sensors for actuation and control of the rotation of the carriage relative to the chassis. The carriage is rotationally supported relative to the chassis about a pivot axis (P) that remains in a static position with respect to the chassis, the carriage having a mass distribution forming a centre of gravity (CG) positioned below the pivot axis (P), the pivot actuation system serving to assist and dampen passive rotation of the carriage relative to the chassis due to the torque generated by centrifugal force acting upon the centre of gravity about the pivot axis (P).
