전원 장치(12)로부터 유도 선로(14)로의 급전을 개시할 때에, 전원 장치(12)의 인버터(24)의 발진 주파수를 공진 회로가 공진하는 주파수로부터 오프셋한 소정 주파수로 하고, 소정 시간의 경과후 소정 주파수로부터 공진 주파수로 변화시킨다. 이로써, 급전 개시시에 모든 반송 대차(17)가 유도 선로(14)로부터 전체 부하 상태로 전력을 취할려고 해도, 각 반송 대차(17)의 공진 회로보다 인출할 수 있는 전력은 작게 되기 때문에, 총전력은 전원 장치(12)가 공급할 수 있는 전력 내로 억제되어 전원 장치(12)가 과부하의 상태로 되는 것이 회피된다.

    At the start of power supply from a power supply device to an induction line, the oscillation frequency of an inverter of the power supply device is set at a predetermined frequency shifted from the resonance frequency of a resonant circuit. After a predetermined time, the frequency is changed from the predetermined frequency to the resonance frequency. Thus, at the start of power supply, only small power is obtained by the resonant circuits in all transport carriages from the induction line in a full-load condition. Thus, total power is suppressed within power that can be supplied by the power supply device, avoiding an overloaded condition of the power supply device.
