Filed: 2019-08-27
Abstract: To provide a device that is able to accurately estimate an error of a voltage sensor regardless of a voltage increase and a voltage non-increase when voltage conversion control is executed by a converter.SOLUTION: A voltage sensor error estimation device for a converter has a first calculation unit (Steps S2-S5) that obtains a correction term with a dead time, based on a difference between feedback duty values in cases of different carrier frequencies. The voltage sensor error estimation device for the converter further has a second calculation unit (Steps S6-S13) that calculates each of errors from four relational expressions in which a feedback duty value in a case where a voltage is increased at four different duty command values is substituted in a calculation formula for a feedback duty value including a correction term, an input-side offset error, an input-side gain error, an output-side offset error, and an output-side gain error. Based on a calculation result from the second calculation unit, errors of an input-side voltage sensor and an output-side voltage sensor are estimated.SELECTED DRAWING: Figure 4
