Abstract
Official abstract text for this publication.
A station building power supply device according to the present invention includes: a station building power generation unit including an inverter main circuit and an inverter control circuit to control the inverter main circuit, in which the inverter main circuit converts a voltage supplied from an overhead wire into a voltage required by loads in a station building; a control-circuit power generation unit that converts a voltage supplied to the loads in the station building and generates an input voltage for the inverter control circuit; and a start-up power generation unit that converts a voltage supplied from the overhead wire and generates an input voltage for the inverter control circuit, in a state where the inverter main circuit has stopped the operation and the control-circuit power generation unit has stopped an operation of generating the input voltage for the inverter control circuit.
First claim
Opening claim text (preview).
The invention claimed is: 1. A station building power supply device comprising: a station building power generator including an inverter main circuit and an inverter control circuit to control the inverter main circuit, in which the inverter main circuit converts a voltage supplied from an overhead wire into a voltage required by loads in a station building; a control-circuit power generator that converts a voltage supplied to the loads in the station building and generates an input voltage for the inverter control circuit; and a start-up power generator that converts a voltage supplied from the overhead wire and generates an input voltage for the inverter control circuit, in a state where operation of the inverter main circuit has stopped and the control-circuit power generator has stopped an operation of generating the input voltage for the inverter control circuit, wherein the start-up power generator stops an operation of generating the input voltage for the inverter control circuit when detecting that the control-circuit power generator has started the operation of generating the input voltage for the inverter control circuit. 2. The station building power supply device according to claim 1 , wherein the start-up power generator stops the operation of generating the input voltage for the inverter control circuit when a predetermined time has passed after the start-up power generator has started to generate the input voltage for the inverter control circuit without detecting that the control-circuit power generator has started the operation of generating the input voltage for the inverter control circuit. 3. The station building power supply device according to claim 1 , wherein the start-up power generator stops the operation of generating the input voltage for the inverter control circuit when a predetermined time has passed after the start-up power generator has started to generate the input voltage for the inverter control circuit without detecting that the control-circuit power generator has started the operation of generating the input voltage for the inverter control circuit. 4. The station building power supply device according to claim 1 , wherein the input voltage for the inverter control circuit is generated by the start-up power generator based on the voltage supplied from the overhead line and received by the start-up power generator. 5. The station building power supply device according to claim 1 , wherein the input voltage for the inverter control circuit is generated by the control-circuit power generator based on the voltage supplied to the loads in the station building. 6. The station building power supply device according to claim 1 , wherein the start-up power generator and the control-circuit power generator are both connected to the inverter control circuit by a common pathway. 7. The station building power supply device according to claim 1 , wherein the start-up power generator and the control-circuit power generator are connected to each other by two pathways. 8. The station building power supply device according to claim 7 , wherein the two pathways are also connected to the inverter control circuit.
