在电气化铁道机车和动车的大功率辅助电源系统中,现一般采用GTO晶闸管开关.基于人们提出的小型轻量、低噪声、电磁干扰小和控制能力强的要求,日本Nagasaki大学的电气工程和计算机科学系的Hirofumi matsuo先生与其他单位合作,开发了一种电气化铁道机车和动车用新型三相 GTO thyristor switches are now commonly used in high-power auxiliary power systems for electrified railway locomotives and motor vehicles. Based on the demands of small size, light weight, low noise, small electromagnetic interference and high controllability, electrical engineering and computers at Nagasaki University in Japan Mr. Hirofumi Matsuo of the Department of Science, in collaboration with other units, has developed a new type of three-phase electric railway locomotive and motor car
