DRIVE DEVICE FOR ELECTRIC ROLLING STOCK

PURPOSE:To suppress the power loss of a field coil to a low value by supplementing the insufficient magnetic flux by the field of an electromagnet at a high load time by using a permanent magnet field only at a low load time. CONSTITUTION:A field control transistor 13 has zero current flow rate in t...
