Title:
MAGLEV TRAIN LINEAR MOTOR POWER SUPPLY CIRCUIT AND METHOD
Document Type and Number:
WIPO Patent Application WO/2018/126821
Kind Code:
A1
Abstract:
A maglev train linear motor power supply circuit. Two sides of each levitation chassis are provided with linear motors. The linear motors on the same sides of levitation chassises on the same train section are connected to each other in series. The linear motors connected in series are divided into series units equal in amount. Series-parallel switch devices are disposed between the series units to achieve series-parallel switching of the series units. Also disclosed a power supply method for the maglev train linear motor power supply circuit. When a train starts to accelerate, the series-parallel switch devices are in a series position, and the series units operate in a series manner; when the train accelerates to a set speed, the series-parallel switch devices are in a parallel position, and the series units operate in parallel manner. The power supply circuit and the power supply method ensure both high-current tractive capacity for a train starting to accelerate and the requirement on high voltage of the linear motors when the train is in high-speed operation, and reduces the temperature rise of the linear motors.
