| Title of Invention | POWER SUPPLY SYSTEM FOR RAILWAY TRAIN WITH TEST SYSTEM. |
|---|---|
| Abstract | A power supply system for a railway train comprises a control circuit of a larger capacity power switching element or IGBT, an input current limit control device, a heat-sink of a fin type, a leakage current detecting device and a test system, in which the control circuit controls the driving of the IGBT having a larger capacity, the input current limit control device includes two switching elements connected in parallel to each other to be operated alternately for the same time period, the heat sink of a circular rod fin type includes a plurality of circular rods constituted as a fin and a base for dissipating the heat of a radiant body, the leakage current detecting device includes a leakage current detecting means for detecting a leakage current from an inverter and a leakage current detecting circuit for judging whether leakage current exists between an output circuit and frame ground FG and the test system includes a program PC including a target supervising program for generating a program source and a target for enabling a system emulation. |
