Abstract
The transport system includes transport modules each including a coil group and an inverter unit that applies an AC voltage to the coil group. The transport system has at least one carriage having a magnet installed thereon to receive an electromagnetic force from the coil group. Each inverter unit includes an inverter circuit and a diode. The inverter circuit has a DC voltage applied thereto, the DC voltage being output from a DC power supply, and converts the DC voltage into the AC voltage. The diode is connected between the DC power supply and the inverter circuit and disposed to allow a current to flow in a forward direction from a first side of the diode connected to the DC power supply to a second side of the diode opposite to the first side when a potential on the first side is higher than a potential on the second side.
