Claim 1:
2. The control device according to claim 1, further comprising:
a circuit controller to control a step-down circuit connected to the primary side of the power converter, the power converter conducting bidirectional power conversion between the primary side and the secondary side, wherein
the circuit controller obtains an operation command including a power running command or a braking command to the railway vehicle, and activates the step-down circuit when the operation command includes the braking command and the voltage at the primary side is equal to or higher than an initial voltage, and
when the separation determiner determines that the current collector is separate from the power line, the circuit controller activates the step-down circuit, even when the voltage at the primary side is lower than the initial voltage.
