초록

In Seoul Metro, Researching VVVF train of Line 4 by HYUNDAI what Changing and Applying State power conversion device IGBT of propulsion control device C/I from GTO. At initial we got a result when installed IGBT mixed GTO that was lack of traction from to imbalance of Output current between applied Type of IGBT(1-car) to applied Type of GTO(4-car). This phenomenon, two kinds of response performance of the IGBT Inverter vehicle to the controller Switching signal for driving the existing GTO Inverter differences in the operating characteristics of the power element is grasped that there is cause to appear unlike GTO car It was, To make balance with two power device when installed IGBT mixed GTO at one train, we installed interface board between the controller because matching the response performance to be generated between the vehicle when the mixed use one train. As a result, to ensure the GTO Type and IGBT Type vehicle between the uniform Switching response performance to verify its compatibility for mixed use, when the train service, was to maintain the normal operating performance and comfortable ride.
