Vehicle auxiliary electric-power-supplying system
First Claim
1. A vehicle auxiliary electric-power-supplying system comprising:
- an electric power inverter for converting first dc power received through an overhead wire to second dc power, and supplying the second dc power to a dc load;
an electric power supplier for converting the first dc power received through the overhead wire to third dc power;
a power-outputting unit, connected to both the electric power inverter and the electric power supplier, for outputting higher dc power of either the second dc power or the third dc power; and
a controller for receiving power from the power-outputting unit, and controlling the electric power inverter,wherein the electric power inverter comprises a charging switch that controls current flowing through the overhead wire, and controls the conversion of the first dc power to the second dc power based on the control signals output from the controller.

Abstract
A vehicle auxiliary electric-power-supplying system can normally stop an electric power inverter by the frequency in use for an electric power supplier being suppressed as low as possible, and electric power being immediately started to be supplied from the power supplier to a controller in a case in which normal electric power has become unable to be obtained from power-outputting of the electric power inverter. The system includes: the electric power inverter for converting a first type of dc power received through an overhead wire to a second type of dc power, and supplying the second type of dc power to a dc load; the power supplier for converting the first type of dc power received through the overhead wire to a third type of dc power; a power-outputting unit, connected to both the electric power inverter and the electric power supplier, for outputting either the second type of dc power or the third type of dc power; and the controller for receiving power from the power-outputting unit, and controlling the electric power inverter.
