Abstract

PURPOSE:To prevent a DC circuit including a main motor from becoming an overcurrent state by reducing the output of a field power source when an electric motor vehicle passes an AC-AC section during a regenerating operation. CONSTITUTION:A main circuit voltage controller 9 and a field voltage controller 23 input a command signal from a master controller 8 and respectively control a thyristor power source 5 and a field thyristor power source 21. When a vehicle element 11 detects a signal from a ground element 12 installed before an AC-AC section SE while an electric motor vehicle carries out a regenerating operation, the controller 9 controls the phase shift to the degree not fail the commutation of the thyristor of the power source 5, and the controller 23 cuts the output of the power source 21, thereby setting the field current to zero. When a vehicle element 11 detects a signal from a ground element 26 installed at the rear of the section SE, the regenerating operations again carried out.
