Title:
DRIVE CONTROL DEVICE AND DRIVE DEVICE FOR RAILROAD CARS
Document Type and Number:
WIPO Patent Application WO/2019/244343
Kind Code:
A1
Abstract:
A drive control device (10) according to the present invention is provided with a main converter (12) that converts an alternating-current power, which is supplied to a primary terminal from a power generator (11) that generates and outputs the alternating-current power by being driven by an internal combustion engine (2), into a direct-current power and outputs the direct-current power from a secondary terminal, or alternatively converts a direct-current power supplied to the secondary terminal into an alternating-current power and supplies the alternating-current power to the power generator (11). The drive control device (1) is also provided with: a first inverter (14) which is connected to the secondary terminal of the main converter (12); and a step-down circuit (17) which steps down the voltage of the direct-current power output from the main converter (12) and supplies the resulting direct-current power to an electricity storage device (16). The internal combustion engine (2) is started by having the power generator (11) operate as a motor using the electricity storage device (16) as a power source. After the internal combustion engine (2) is started, the direct-current power output from the main converter (12) is supplied to the first inverter (14), while being also supplied to the electricity storage device (16) after having the voltage stepped down by means of the step-down circuit (17).
