FIELD: electrical engineering.
SUBSTANCE: voltage converter comprises a first voltage sensor and a second voltage sensor configured to measure voltage output of the voltage converter circuit, and a controller configured to perform feedback control by the voltage converter circuit such that the difference between the target voltage and the measured value of the first voltage sensor is zero, and also configured to perform a predetermined emergency process in case the measured value of the second voltage sensor exceeds a predetermined upper limit value of voltage.
EFFECT: controller performs feedback control such that the difference between the corrected target voltage and the measured value of the first voltage sensor is zero, when measured value of second voltage sensor exceeds threshold value of voltage, which is lower than upper limit value of voltage.
