Abstract
A power conversion system includes a transformer, a power conversion device for travel, a power conversion device for auxiliary power sources, an electrical storage device, and an auxiliary device. The power conversion device for travel converts AC power into power for travel and supplies it to a travel motor. The power conversion device for auxiliary power sources includes an AC to DC conversion unit which converts AC power into DC power, a power conversion unit for AC loads which converts the DC power into AC power and supplies it to an AC load, and a power conversion unit for DC loads which converts DC power to DC power and supplies it to a DC load. The electrical storage device is connected to power lines connecting DC power output terminals of the AC to DC conversion unit and DC power input terminals of both the power conversion units for AC and DC loads. The auxiliary device is connected to power lines connecting the power conversion device for auxiliary power sources and the electrical storage device and operates with power supplied from the electrical storage device.
