電気車制御装置
Document Type and Number:
Japanese Patent JP4568169
Kind Code:
B2
Abstract:
A control system for centrally controlling information related to an electric motor car and effectively using power for the electric motor car involves a VVVF inverter, a CVCF inverter, a fuel cell, a power storage unit, and a power management unit that centrally controls power of the electric motor car. When the electric motor car carries out a regenerative braking operation, the power management unit makes the VVVF inverter convert AC power regenerated by a motor into DC power and makes the power storage unit and CVCF inverter store and consume the converted DC power. When the electric motor car carries out a power running operation, the power management unit supplies power from the fuel cell and power storage unit and supplemental power from an overhead line to the VVVF inverter and CVCF inverter. When the electric motor car carries out a coasting operation, the power management unit supplies power from the fuel cell and power storage unit and supplemental power from the overhead line to the CVCF inverter.
