Claims

[Scope of utility model registration request]

Multiple forward power converters that are operated in parallel and have a fault current cutoff function that converts AC power to DC power, DC busbars connected to the output side of these forward power converters, and a dead section between the DC busbars and dead sections. a power line diode which is inserted in series with the electric line connecting the first and second overhead contact lines, and one of the first and second overhead contact lines is separated by a predetermined pressure from the dead section a third overhead contact line formed by providing a dead section; a regenerative thyristor circuit breaker inserted in the electric line connecting the third overhead contact line and the DC bus; and a cathode on the anode side of the thyristor circuit breaker. A pair of diodes each having an anode side connected to the cathode side of the power running diode, and a power transmission line that is connected to the DC bus and converts the regenerated power of each of the overhead contact lines into AC power. A power supply device for a DC electric railway, comprising: a reverse power converter for supplying power to a DC electric railway;
