| Abstract;Hitachi has been developing the converter/inverter equipment, auxiliary power unit, airless line breaker, and electronic master controller by applying the vector control and high voltage resistance IGBT (Insulated Gate Bipolar Transistor) for the rapid improvement in capability, maintainability and efficiency. Recently, in the power system of diesel railway cars, the needs to cut-back on maintenance, to increase the efficiency, and to improve the environment are desired. And in the system of electric railwat cars, the compactness and lightness in weight are requested. Therefore, Hitachi has developed the following systems jointly with East Japan Railway Co.,Ltd : (1)hybrid power system which applied the technology of electric system for electric railway cars to the power system of diesel railcar, and 2) small cooling system based on the water circulation system. In addition, the technology which use the speed sensorless control in combination with a full electric brake control is developed. |
