摘要： A dual start control circuit for auxiliary inverters of a railway vehicle is provided. An external dual circuit is designed for controlling a start and stop of the auxiliary inverters; and an APS START signal is added to start conditions of the auxiliary inverters. When a start-stop switch is turned to an “on” position, an APS start train line is electrified, APS start relays in cabs at both ends are electrified and corresponding normally-open contacts of the APS start relays are closed, a self-locking circuit is kept electrified, the APS start train line is kept electrified, and a start signal is transmitted to the auxiliary inverters through a hard wire; and when the start-stop switch is turned to an “off” position, an APS stop train line is electrified, APS stop relays in the cabs at both ends are electrified and corresponding normally-closed contacts of the APS stop relays are disconnected.
