Title:
POWER CONVERSION APPARATUS
Document Type and Number:
Japanese Patent JP2015186317
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a technique for suppressing an influence caused by deterioration of current measurement accuracy while adopting plural coreless current sensors in a power conversion apparatus specifically used for an electric vehicle that includes a main motor and a sub-motor for traveling.SOLUTION: A power conversion apparatus includes: a first inverter circuit 22 for supplying power to a main motor 7 capable of driving a vehicle independently; a second inverter circuit 21 for supplying power to a sub-motor 6 with a maximum output smaller than that of the main motor 7; a first bus set 15 for transmitting an output of the first inverter circuit 22; and a second bus set 14 for transmitting an output of the second inverter circuit 21. An individual bus bar of the first bus set 15 is provided with a first current sensor 17 accompanied by a collection core. An individual bus bar of the second bus set 14 is provided with a second current sensor 16 unaccompanied by a collection core.
