Title:
Boost converter arrangement
Document Type and Number:
Japanese Patent JP6233178
Kind Code:
B2
Abstract:
A boost converter device includes a converter, a current sensor which detects a reactor current flowing through a reactor, and a control unit which controls the converter by using feedback control of the reactor current. The control unit executes at least one of reducing a carrier frequency which is used in the control of the converter and reducing a duty command value which is used in the control of the converter, detects an amplitude of current ripple by the current sensor during execution of the reduction of the carrier frequency or the reduction of the duty command value, and detects the current sensor as being abnormal in a case where the amplitude of the current ripple is less than a predetermined current fluctuation range at the time of abnormality of the current sensor.
