Title:
電力システム
Document Type and Number:
Japanese Patent JP6406733
Kind Code:
B2
Abstract:
Provided is an electric power system capable of rapidly slowing an electric motor and quickly discharging a capacitor when an abnormality occurs. If an abnormality detection device detects an abnormality, a control device of an electric power system performs a switching control that alternately switches between an upper arm three-phase short-circuit control that sets all upper arms to a conductive state and sets all lower arms to a non-conductive state, and a lower arm three-phase short-circuit control that sets all upper arms to a non-conductive state and sets all lower arms to a conductive state. When switching between the two short-circuit controls, a conduction overlap period in which the conductive state of said upper arms and the conductive state of said lower arms overlap may be generated.
