Abstract

PURPOSE: To restrict the surge voltage occurred when a switch is opened by a simple circuit configuration by reducing an electric current flowing through a chngeover switch after stopping operation of a cyclone converter and opening the switch after the reduction of current.
CONSTITUTION: Two cyclone converters control alternative energization of propulsive coils in a number of zones. Opening or closure instructing circuits 8∼11 consisting of AC breakers K1, K2, power transformers T1, T2, a counter for instructing the opening or closure of the breakers K1, K2 and a memory are provided, and cross induction lines 20 are laid along a track. A receiver is connected to the lines 20 for receiving signals from a transmitter and antenna carried on a vehicle 1 to thereby detect the relative position between the field 2 and the propulsive coil carried on the vehicle 1. Thus, the circuit configuration can be simplified by opening a changeover switch after stopping the operation of the converters to thereby restrict the surge voltage when the switch is opened.
