METHOD OF COMPENSATING SENSING-OFFSET OF INVERTER AND APPARATUS THEREOF

摘要

A method for compensating sensing-offset of an inverter and an apparatus thereof are disclosed. According to an embodiment of the present invention, the apparatus for compensating sensing-offset of an inverter subtracts an offset average value from reference voltages ofα-shaft andβ-shaft of a Stationary Reference Frame of an inverter controller, after calculating the offset average values ofα-shaft andβ-shaft for a certain period by sampling the reference voltages ofα-shaft andβ-shaft of a Stationary Reference Frame of the inverter controller.
